We have found that in certain circumstances, Excel will crash when you type data into a cell and press &amp;lt;&lt;strong&gt;Enter&lt;/strong&gt;&amp;gt;. The same crash may occur when you select data and click the &lt;strong&gt;Quick Analysis&lt;/strong&gt; button. We are currently investigating the issue, but it has been confirmed to be related to Flash Fill and Quick Analysis, and it only occurs in 32-bit Excel. It most often occurs when data has been imported from OLAP data sources, and copied to a new location. If you look at the crash report, the crash application will be Excel.exe, and the Module will be listed as ntdll.dll.&lt;/p&gt;
&lt;p&gt;We have a couple of workarounds:&lt;/p&gt;
&lt;p&gt;Workaround 1:&lt;/p&gt;
&lt;ol&gt;
&lt;li&gt;&lt;span style="font-family: Calibri; font-size: small;"&gt;Click on &lt;strong&gt;File&lt;/strong&gt; --&amp;gt; &lt;strong&gt;Options&lt;/strong&gt; --&amp;gt; &lt;strong&gt;Advanced&lt;/strong&gt;.&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style="font-family: Calibri; font-size: small;"&gt;In the Editing Options section, clear the checkbox for &lt;strong&gt;Automatically Flash Fill&lt;/strong&gt;.&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style="font-family: Calibri; font-size: small;"&gt;Click on the &lt;strong&gt;General&lt;/strong&gt; tab.&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style="font-family: Calibri; font-size: small;"&gt;Clear &lt;strong&gt;Show Quick Analysis&lt;/strong&gt; &lt;strong&gt;options on selection&lt;/strong&gt;.&lt;/span&gt;&lt;/li&gt;
&lt;/ol&gt;
&lt;p&gt;&lt;span style="font-family: Calibri; font-size: small;"&gt;Workaround 2: &lt;/span&gt;&lt;/p&gt;
&lt;ol&gt;
&lt;li&gt;&lt;span style="font-family: Calibri; font-size: small;"&gt;In your &lt;strong&gt;Data&lt;/strong&gt; tab, click &lt;strong&gt;Connections&lt;/strong&gt;.&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style="font-family: Calibri; font-size: small;"&gt;Click the &lt;strong&gt;Properties...&lt;/strong&gt; button.&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style="font-family: Calibri; font-size: small;"&gt;Clear the checkboxes under &lt;strong&gt;OLAP Server Formatting.&lt;/strong&gt;&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style="font-family: Calibri; font-size: small;"&gt;Import your data.&lt;/span&gt;&lt;/li&gt;
&lt;/ol&gt;
&lt;p&gt;&lt;span style="font-family: Calibri; font-size: small;"&gt;Either of these should temporarily resolve the issue. We will update this blog as new information becomes available. If this blog helps you resolve crashes in Excel, please leave a comment.&lt;/span&gt;&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;&lt;img src="http://blogs.technet.com/aggbug.aspx?PostID=3571175" width="1" height="1"&gt;</content><author><name>Anita [MSFT]</name><uri>http://blogs.technet.com/anitaoakley_2D00_msft_4000_hotmail.com/ProfileUrlRedirect.ashx</uri></author></entry><entry><title>How to Troubleshoot Memory Errors in Excel; "Available Resources", "Out of Memory", "System Resources"</title><link rel="alternate" type="text/html" href="http://blogs.technet.com/b/the_microsoft_excel_support_team_blog/archive/2013/04/19/how-to-troubleshoot-memory-errors-in-excel-quot-available-resources-quot-quot-out-of-memory-quot-quot-system-resources-quot.aspx" /><id>http://blogs.technet.com/b/the_microsoft_excel_support_team_blog/archive/2013/04/19/how-to-troubleshoot-memory-errors-in-excel-quot-available-resources-quot-quot-out-of-memory-quot-quot-system-resources-quot.aspx</id><published>2013-04-19T19:31:00Z</published><updated>2013-04-19T19:31:00Z</updated><content type="html">&lt;p&gt;Thanks for the feedback the &amp;ldquo;available resources&amp;rdquo; post!&amp;nbsp; We realized that many people are getting these type of memory issues in Excel and are looking for some answers. &amp;nbsp;So we wrote a detailed KB that addresses most of the common memory issues.&lt;/p&gt;
&lt;p&gt;If you are seeing any of the following messages;&lt;/p&gt;
&lt;ul&gt;

&lt;p&gt;&lt;span style="font-size: small;"&gt;Access:&lt;/span&gt;&lt;/p&gt;
&lt;ul&gt;
&lt;li&gt;&lt;span style="font-size: small;"&gt;When running wizards the receive the following error,&amp;nbsp; &lt;span style="color: #ff0000;"&gt;&lt;em&gt;&amp;ldquo;This feature isn't installed, or has been disabled"&lt;/em&gt;&lt;/span&gt;&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style="font-size: small;"&gt;When opening VBA editor the user receives &lt;span style="color: #ff0000;"&gt;&lt;em&gt;&amp;ldquo;Microsoft Access is unable to load the Visual Basic for &lt;/em&gt;&lt;/span&gt;&lt;/span&gt;&lt;span style="color: #ff0000;"&gt;&lt;em&gt;&lt;span style="font-size: small;"&gt;Applications dynamic-link library (dll) Vbe7" when opening the Visual Basic Editor (VBE)&amp;rdquo;&lt;/span&gt;&lt;/em&gt;&lt;/span&gt;&lt;/li&gt;
&lt;/ul&gt;
&lt;p&gt;&lt;span style="font-size: small;"&gt;Excel&lt;/span&gt;&lt;/p&gt;
&lt;ul&gt;
&lt;li&gt;&lt;span style="font-size: small;"&gt;The Visual Basic, Macros and Record Macro options are disabled/greyed on the ribbon.&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style="font-size: small;"&gt;When opening workbooks with VBA code, the user receive the following message,&lt;em&gt;&lt;span style="color: #ff0000;"&gt; &amp;ldquo;The Visual Basic for &lt;/span&gt;&lt;/em&gt;&lt;/span&gt;&lt;em&gt;&lt;span style="color: #ff0000; font-size: small;"&gt;Applications (VBA) macros in this workbook are corrupted and have been deleted."&lt;/span&gt;&lt;/em&gt;&lt;/li&gt;
&lt;/ul&gt;
&lt;p&gt;&lt;span style="font-size: small;"&gt;Word&lt;/span&gt;&lt;/p&gt;
&lt;ul&gt;
&lt;li&gt;&lt;span style="font-size: small;"&gt;The Macro button is not greyed out but when trying to run or record a macro they receive the following&lt;/span&gt;&lt;br /&gt;&lt;span style="font-size: small;"&gt;message, &lt;em&gt;&lt;span style="color: #ff0000;"&gt;&amp;ldquo;The function you are attempting to run contains macros or content that requires macro language support"&lt;/span&gt;&lt;/em&gt;&lt;/span&gt;&lt;/li&gt;
&lt;/ul&gt;
&lt;p&gt;&lt;br /&gt;&lt;span style="font-size: small;"&gt;&lt;span style="font-family: Arial;"&gt;PowerPoint&lt;/span&gt;&lt;/span&gt;&lt;/p&gt;
&lt;ul&gt;
&lt;li&gt;&lt;span style="font-family: Arial; font-size: small;"&gt;The Visual Basic, and Macros options are disabled/greyed on the ribbon.&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style="font-family: Arial; font-size: small;"&gt;When opening presentations with VBA code, the user receive the following message:&lt;br /&gt;&lt;span style="color: #ff0000;"&gt;&lt;em&gt;"The document contains macros. Macro language support for this application is disabled.&amp;nbsp; &lt;/em&gt;&lt;/span&gt;&lt;span style="color: #ff0000;"&gt;&lt;em&gt;Features requiring VBA are not available. Would you like to open this document read-only?"&lt;/em&gt;&lt;/span&gt;&lt;/span&gt;&lt;/li&gt;
&lt;/ul&gt;
&lt;p&gt;&amp;nbsp;&lt;/p&gt;
&lt;p&gt;&lt;span style="font-size: small;"&gt;In most cases repairing MS Office fixes the issue. &amp;nbsp;&amp;nbsp;&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span style="font-size: small;"&gt;What we believe is happening is there is a registry cleaner or system maintenance type application removing some our registry keys that we&lt;/span&gt;&lt;br /&gt;&lt;span style="font-size: small;"&gt;need for VBA to run successfully.&amp;nbsp; In the above scenarios when the MS Office application was installed the VBA worked properly.&lt;/span&gt;&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;&lt;img src="http://blogs.technet.com/aggbug.aspx?PostID=3566321" width="1" height="1"&gt;</content><author><name>Laura Holzwarth-Struck</name><uri>http://blogs.technet.com/lauraholzwarth_4000_hotmail.com/ProfileUrlRedirect.ashx</uri></author><category term="VBA not functional" scheme="http://blogs.technet.com/b/the_microsoft_excel_support_team_blog/archive/tags/VBA+not+functional/" /></entry><entry><title>Problem Reopening Excel 2013 PivotTable Workbooks</title><link rel="alternate" type="text/html" href="http://blogs.technet.com/b/the_microsoft_excel_support_team_blog/archive/2013/03/22/problem-reopening-excel-2013-pivottable-workbooks.aspx" /><id>http://blogs.technet.com/b/the_microsoft_excel_support_team_blog/archive/2013/03/22/problem-reopening-excel-2013-pivottable-workbooks.aspx</id><published>2013-03-22T15:27:01Z</published><updated>2013-03-22T15:27:01Z</updated><content type="html">&lt;p&gt;We&amp;rsquo;ve had a few reports recently from people who have built new PivotTables in Excel 2013, and when they try to reopen the book, receive a message saying:&lt;/p&gt;
&lt;p style="padding-left: 30px;"&gt;&lt;em&gt;We found a problem with some&lt;br /&gt;content in &amp;lt;filename&amp;gt;. Do you want us to try to recover as much as we can? If you trust the source of this workbook, click Yes.&lt;/em&gt;&lt;/p&gt;
&lt;p&gt;When they click &amp;ldquo;Yes,&amp;rdquo; and the file opens, they see a second message:&lt;/p&gt;
&lt;p style="padding-left: 30px;"&gt;&lt;em&gt;Removed Part: /xl/pivotCache/pivotCacheDefinition1.xml part with XML&lt;br /&gt;error.&amp;nbsp; (PivotTable cache) Load error. Line 2, column 0.&lt;/em&gt;&lt;/p&gt;
&lt;p style="padding-left: 30px;"&gt;&lt;em&gt;Removed Feature: PivotTable&lt;br /&gt;report from /xl/pivotTables/pivotTable1.xml part (PivotTable view)&lt;/em&gt;&lt;/p&gt;
&lt;p&gt;&amp;nbsp;The data associated with the PivotTable is still there, but the PivotTable no longer functions. This can also occur if you open a PivotTable from Excel 2010 is opened in Excel 2013, the data refreshed, and the file saved. When you try to reopen the file, it reports a problem with the content.&lt;/p&gt;
&lt;p&gt;We have found that this will occur if Excel tries to read a 0 value in where it expects a date. Microsoft is currently investigating the issue further. In the meantime, you can work around this issue as follows:&lt;/p&gt;
&lt;ol&gt;
&lt;li&gt;Right Click on the PivotTable&lt;br /&gt;Click PivotTableOptions&lt;/li&gt;
&lt;li&gt;On the Display tab, clear the checkbox labeled&lt;br /&gt;&amp;ldquo;Show Properties in ToolTips.&amp;rdquo;&lt;/li&gt;
&lt;li&gt;Save the file with the new setting intact. Note:&lt;br /&gt;If you fail to use the workaround before saving and closing the file, we cannot&lt;br /&gt;recover the PivotTable.&lt;/li&gt;
&lt;/ol&gt;
&lt;p&gt;For an explanation about how Excel stores dates as serial numbers, see &lt;a href="http://support.microsoft.com/kb/214094"&gt;http://support.microsoft.com/kb/214094&lt;/a&gt;.&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;&lt;img src="http://blogs.technet.com/aggbug.aspx?PostID=3560420" width="1" height="1"&gt;</content><author><name>Anita [MSFT]</name><uri>http://blogs.technet.com/anitaoakley_2D00_msft_4000_hotmail.com/ProfileUrlRedirect.ashx</uri></author><category term="Excel15" scheme="http://blogs.technet.com/b/the_microsoft_excel_support_team_blog/archive/tags/Excel15/" /><category term="Corrupt" scheme="http://blogs.technet.com/b/the_microsoft_excel_support_team_blog/archive/tags/Corrupt/" /><category term="PivotTable" scheme="http://blogs.technet.com/b/the_microsoft_excel_support_team_blog/archive/tags/PivotTable/" /></entry><entry><title>How to: Use the Open XML SDK 2.0 in Visual Studio 2010 to create a simple Excel Spreadsheet (in C#)</title><link rel="alternate" type="text/html" href="http://blogs.technet.com/b/the_microsoft_excel_support_team_blog/archive/2013/03/04/how-to-use-the-open-xml-sdk-2-0-in-visual-studio-2010-to-create-a-simple-excel-spreadsheet-in-c.aspx" /><id>http://blogs.technet.com/b/the_microsoft_excel_support_team_blog/archive/2013/03/04/how-to-use-the-open-xml-sdk-2-0-in-visual-studio-2010-to-create-a-simple-excel-spreadsheet-in-c.aspx</id><published>2013-03-04T22:27:21Z</published><updated>2013-03-04T22:27:21Z</updated><content type="html">&lt;p&gt;There are plenty of examples out on the internet to use the Open XML SDK 2.0 and Visual Studio 2010 to create Excel workbooks. I wanted to create my own how-to because the other examples I found seemed overly complex and some lacked basic information such as what references and namespaces need to be included.&lt;/p&gt;
&lt;p&gt;1. Install the Open XML SDK 2.0 from &lt;a href="http://www.microsoft.com/en-us/download/details.aspx?id=5124" target="_blank"&gt;here&lt;/a&gt;. You will want to download and install both the &lt;span&gt;OpenXMLSDKTool.msi and &lt;span&gt;OpenXMLSDKv2.msi&lt;/span&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;2. Once installed, Launch Visual Studio 2010. Create a new Windows Console Application under C#. Give your Console Application a name and click OK&lt;/p&gt;
&lt;p&gt;3. The project is then created. Now you need to add references. Click Project &amp;gt; Add Reference and under the .NET tab look for "DocumentFormat.OpenXML". Click this reference and click OK. Again, Click Project &amp;gt; Add Reference and under the .NET tab look for "WindowsBase". Select this reference and click OK.&lt;/p&gt;
&lt;p&gt;4. In your code, add the following namespaces:&lt;/p&gt;
&lt;p&gt;using System.IO;&lt;br /&gt;using DocumentFormat.OpenXml;&lt;br /&gt;using DocumentFormat.OpenXml.Packaging;&lt;br /&gt;using DocumentFormat.OpenXml.Spreadsheet;&lt;/p&gt;
&lt;p&gt;5. Under your "program" class, find "Static void Main (string[] args)". After the closing terminator add the following method:&lt;/p&gt;
&lt;p&gt;public static void CreateSpreadsheetWorkbook(string filepath)&lt;br /&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; {&lt;br /&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; // Create a spreadsheet document by supplying the filepath.&lt;br /&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; // By default, AutoSave = true, Editable = true, and Type = xlsx.&lt;br /&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; &lt;br /&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; SpreadsheetDocument spreadsheetDocument = SpreadsheetDocument.Create(filepath, SpreadsheetDocumentType.Workbook);&lt;/p&gt;
&lt;p&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; // Add a WorkbookPart to the document.&lt;br /&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; WorkbookPart workbookpart = spreadsheetDocument.AddWorkbookPart();&lt;br /&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; workbookpart.Workbook = new Workbook();&lt;/p&gt;
&lt;p&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; // Add a WorksheetPart to the WorkbookPart.&lt;br /&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; WorksheetPart worksheetPart = workbookpart.AddNewPart&amp;lt;WorksheetPart&amp;gt;();&lt;br /&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; worksheetPart.Worksheet = new Worksheet(new SheetData());&lt;/p&gt;
&lt;p&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; // Add Sheets to the Workbook.&lt;br /&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; Sheets sheets = spreadsheetDocument.WorkbookPart.Workbook.AppendChild&amp;lt;Sheets&amp;gt;(new Sheets());&lt;/p&gt;
&lt;p&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; // Append a new worksheet and associate it with the workbook.&lt;br /&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; Sheet sheet = new Sheet() { Id = spreadsheetDocument.WorkbookPart.GetIdOfPart(worksheetPart), SheetId = 1, Name = "mySheet" };&lt;br /&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; sheets.Append(sheet);&lt;/p&gt;
&lt;p&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; workbookpart.Workbook.Save();&lt;/p&gt;
&lt;p&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; // Close the document.&lt;br /&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; spreadsheetDocument.Close();&lt;br /&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; }&lt;/p&gt;
&lt;p&gt;6. In your&amp;nbsp;Main method, add the following line of code:&lt;/p&gt;
&lt;p&gt;&amp;nbsp;CreateSpreadsheetWorkbook("C:\\Test\\Test.xlsx");&lt;/p&gt;
&lt;p&gt;The entire method will look like this: &lt;br /&gt;&lt;br /&gt;static void Main(string[] args)&lt;br /&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; {&lt;br /&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; CreateSpreadsheetWorkbook("C:\\Test\\Test.xlsx");&lt;br /&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; }&lt;/p&gt;
&lt;p&gt;What we are doing here is calling the &amp;nbsp;CreateSpreadsheetWorkbook method and telling it to create our basic spreadsheet in a directory on the C:\ drive called Test. We are also assigning a name to the workbook of "Text.XLSX" (if we didn't assign a name you would see an "Access Denied" error when the code is run"). Also, you will want to make sure the directory exists or else you will get a "DirectoryNotFoundException" during runtime.&lt;/p&gt;
&lt;p&gt;At this point you should save the project and run it. If you have a directory C:\Test you should see a workbook called "Text.XLSX" appear in that folder. This is a very basic spreadsheet. It contains no data and only a single sheet called "mySheet". This is done by the two lines of code in the CreateSpreadsheetWorkbook method.&lt;/p&gt;

In addition, you&amp;nbsp;will be prompted with an error message that asks you to upgrade the data model:&lt;/p&gt;
&lt;p&gt;&lt;a href="http://blogs.technet.com/cfs-file.ashx/__key/communityserver-blogs-components-weblogfiles/00-00-00-87-63/7870.PowerPivotError.png"&gt;&lt;img src="http://blogs.technet.com/resized-image.ashx/__size/550x0/__key/communityserver-blogs-components-weblogfiles/00-00-00-87-63/7870.PowerPivotError.png" alt="" border="0" /&gt;&lt;/a&gt;&lt;/p&gt;
&lt;p&gt;However, when you try to enable the PowerPivot add-in, you may not see it in the COM add-ins dialog box. This problem can happen because in Excel 2013, PowerPivot and the two new add-ins - PowerView and Inquire, are only available on certain SKUs (versions). These include:&lt;/p&gt;
&lt;ul&gt;
&lt;li&gt;&lt;a href="http://office.microsoft.com/en-us/professional-plus/" target="_blank"&gt;Office 2013 Professional Plus&lt;/a&gt; (available through Volume Licensing, MSDN and TechNet subscriptions)&lt;/li&gt;
&lt;li&gt;&lt;a href="http://office.microsoft.com/en-us/business/office-365-proplus-virtual-office-online-FX103213513.aspx" target="_blank"&gt;Office 365 Professional Plus - available as standalone subscription&lt;/a&gt;&lt;/li&gt;
&lt;li&gt;Office 365 Professional Plus (available as part of the &lt;a href="http://office.microsoft.com/en-us/business/office-365-for-mid-sized-businesses-business-productivity-FX103037683.aspx" target="_blank"&gt;Office 365 Mid-Size Business&lt;/a&gt;, &lt;a href="http://office.microsoft.com/en-us/business/office-365-for-enterprise-document-sharing-FX103030346.aspx" target="_blank"&gt;Office 365 Enterprise Plan 3&lt;/a&gt;, or &lt;a href="http://office.microsoft.com/en-us/business/office-365-for-enterprise-document-sharing-FX103030346.aspx" target="_blank"&gt;Office 365 Enterprise Plan 4 offerings&lt;/a&gt;)&lt;/li&gt;
&lt;/ul&gt;
&lt;p&gt;If you have purchased an Office 2013 or Office 365 SKU other than those listed above, you will need to return your product to the place of purchase or stop your current subscription to change to one of the products that does support these add-ins.&lt;/p&gt;
&lt;p&gt;&lt;span style="font-size: x-large;"&gt;Workarounds&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;There are a couple of ways to work around this issue:&lt;/p&gt;
&lt;p&gt;&lt;span style="font-size: medium;"&gt;&lt;strong&gt;Access a machine that has one of the above-listed SKUs&lt;/strong&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;If you have access to a machine that has one of the above listed SKUs, you can use the PowerPivot add-in on that machine to update the PivotTable and save the file. Once the PowerPivot data model is updated, then you can open and use the PivotTables on your other machines. Keep in mind that once updated, you cannot use the PivotTable in Excel 2010&lt;/p&gt;
&lt;p&gt;&lt;span style="font-size: medium;"&gt;&lt;strong&gt;Recreate the&amp;nbsp;Workbook in 2013&lt;/strong&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;If you do not have access to a machine with the PowerPivot 2013 add-in, you can rebuild your PivotTable in Excel 2013. There is no way to update the model, so you will need to import your data again and recreate the&amp;nbsp;workbook from scratch. The data model engine is a part of Excel 2013. To do that:&lt;/p&gt;
&lt;ol&gt;
&lt;li&gt;
&lt;p&gt;If you have tables in Excel that you want to use, do the following.&lt;/p&gt;
&lt;/li&gt;
&lt;ol&gt;
&lt;li&gt;Select a cell in one of the tables.&lt;/li&gt;
&lt;li&gt;On the &lt;strong&gt;Insert&lt;/strong&gt; tab, click on &lt;strong&gt;PivotTable&lt;/strong&gt;.&lt;/li&gt;
&lt;li&gt;Check &lt;strong&gt;Add this data to the Data Model&lt;/strong&gt;.&lt;/li&gt;
&lt;li&gt;Click &lt;strong&gt;Ok&lt;/strong&gt;. Your PivotTable will be created.&lt;/li&gt;
&lt;li&gt;In the &lt;strong&gt;Fields List&lt;/strong&gt;, click the &lt;strong&gt;All&lt;/strong&gt; tab. At this point you can add data from your other tables.&lt;/li&gt;
&lt;li&gt;You may need to create relationships between the tables. You can do that on the &lt;strong&gt;Data&lt;/strong&gt; ribbon or the &lt;strong&gt;PivotTable Tools&lt;/strong&gt;/&lt;strong&gt;Analyze&lt;/strong&gt; ribbon.&lt;/li&gt;
&lt;/ol&gt;
&lt;li&gt;If you are importing data from multiple tables in a single external data source, do the following.&lt;/li&gt;
&lt;ol&gt;
&lt;li&gt;Choose to use an external data source.&lt;/li&gt;
&lt;li&gt;Choose a connection that includes multiple data tables. When the PivotTable is created, the data will be added to the data model automatically.&lt;/li&gt;
&lt;li&gt;In the &lt;strong&gt;Fields List&lt;/strong&gt;, click the &lt;strong&gt;All&lt;/strong&gt; tab, and add data from your tables.&lt;/li&gt;
&lt;/ol&gt;
&lt;li&gt;If you have mixed data, do the following&lt;/li&gt;
&lt;ol&gt;
&lt;li&gt;Import the data into Excel tables first.&lt;/li&gt;
&lt;li&gt;Create any necessary relationships.&lt;/li&gt;
&lt;li&gt;Follow the instructions in item 1.&lt;/li&gt;
&lt;/ol&gt;&lt;/ol&gt;

&lt;p&gt;The two new COM add-ins for Excel Power View and Inquire also require the same SKUS of Excel that PowerPivot does. You can find out more about the Power View add-in at &lt;a href="http://blogs.office.com/b/microsoft-excel/archive/2012/10/04/intro-to-power-view-for-excel-2013.aspx"&gt;http://blogs.office.com/b/microsoft-excel/archive/2012/10/04/intro-to-power-view-for-excel-2013.aspx&lt;/a&gt;.&lt;/p&gt;

&lt;p&gt;This problem can happen when the DisplayLinkManager driver is installed on the system. This problem is known to happen with DisplayLinkDriver versions 5.5.29055.0 or 5.6.30272.0.&lt;/p&gt;
&lt;p&gt;To resolve this problem, update the DisplayLink driver. To do this, connect to&amp;nbsp;&lt;a href="http://www.displaylink.com/support/downloads.php"&gt;http://www.displaylink.com/support/downloads.php&lt;/a&gt;&amp;nbsp;and install any version of the DisplayLinkDriver later than 5.6.30272.0.&lt;/p&gt;
&lt;p&gt;&amp;nbsp;&lt;strong&gt;Note:&amp;nbsp;&lt;/strong&gt; The other Office Applications (Access, Word, PowerPoint, Outlook)&amp;nbsp;will also crash if using the old DisplayLinkDriver.&amp;nbsp; &amp;nbsp;&lt;/p&gt;

&lt;p&gt;Troubleshooting crashes in Excel be difficult. To assist you in this endeavor, we have published a&amp;nbsp;two articles that walks you through a list of&amp;nbsp;several methods and advanced troubleshooting steps&amp;nbsp;involving hangs and crashes in Excel. These include:&lt;/p&gt;
&lt;ul&gt;
&lt;li&gt;Verify/install the latest updates&lt;/li&gt;
&lt;li&gt;Start Excel in safe mode&lt;/li&gt;
&lt;li&gt;Investigate possible issues with add-ins&lt;/li&gt;
&lt;li&gt;Check whether your antivirus software is up to date or is conflicting with Excel&lt;/li&gt;
&lt;li&gt;Make sure that Excel is not being used by another process&lt;/li&gt;
&lt;li&gt;Check whether your file is being generated by a third party&lt;/li&gt;
&lt;li&gt;Test by using a new local or network profile&lt;/li&gt;
&lt;li&gt;Perform a selective startup to determine whether a program, process, or service conflicts with Excel&lt;/li&gt;
&lt;li&gt;Repair or reinstall your Office program&lt;/li&gt;
&lt;/ul&gt;

&lt;p&gt;Hello everyone, we want to bring an emerging issue to your attention today. We have seen several reports of the error below in Microsoft Excel:&lt;/p&gt;
&lt;p&gt;&lt;a href="http://blogs.technet.com/cfs-file.ashx/__key/communityserver-blogs-components-weblogfiles/00-00-00-87-63/6242.clipboarderror.png"&gt;&lt;img src="http://blogs.technet.com/resized-image.ashx/__size/550x0/__key/communityserver-blogs-components-weblogfiles/00-00-00-87-63/6242.clipboarderror.png" alt="" border="0" /&gt;&lt;/a&gt;&lt;/p&gt;
&lt;p&gt;This occurs in multiple versions of Excel when you either cut and paste cells or drag them to move the contents from one location to another.&lt;/p&gt;
&lt;p&gt;(Updated) We have narrowed this down to a conflict with the Bing Desktop Search Bar. If you have the Bing Desktop installed and run up against this issue, you can resolve the problem by updating to Bing Desktop 1.1.166.0 or later. You should receive the fix through Microsoft Update, assuming that you have automatic updates set. &lt;br /&gt;&lt;br /&gt;However, if you are currently experiencing this problem, you can:&lt;br /&gt;&lt;br /&gt;1.&amp;nbsp;Check for updates to see if the Bing Desktop update is listed. If so, update your system.&lt;br /&gt;2.&amp;nbsp;Uninstall Bing Desktop through Control Panel  Programs and Features, and then install the new version from &lt;a href="http://www.microsoft.com/en-us/download/details.aspx?id=35844"&gt;http://www.microsoft.com/en-us/download/details.aspx?id=35844&lt;/a&gt;&lt;/p&gt;
&lt;p&gt;&amp;nbsp;For more information about the Bing Desktop, see &lt;a href="http://www.microsoft.com/en-us/download/details.aspx?id=35844"&gt;http://www.microsoft.com/en-us/download/details.aspx?id=35844&lt;/a&gt;.&lt;/p&gt;

&lt;p&gt;Performance issues are some of our biggest call generators. Users get frustrated with Excel when they upgrade to later versions. Performance issues often boil down to spreadsheets that have been around a long time and&amp;nbsp;the design. Here are some of the common problem areas:&lt;/p&gt;
&lt;p&gt;&lt;strong&gt;Slow Opening:&lt;/strong&gt; Opening an Excel file the first time may be slow if you have a large number of calculations.&amp;nbsp; Excel needs to recalculate the file and verify the values in the workbook.&amp;nbsp; See KB&amp;rsquo;s below for more information.&amp;nbsp;&amp;nbsp;&lt;/p&gt;
&lt;p style="padding-left: 30px;"&gt;210162 - Workbook loads slowly the first time that it is opened in Excel&lt;br /&gt;&lt;a href="http://support.microsoft.com/default.aspx?scid=kb;EN-US;210162"&gt;http://support.microsoft.com/default.aspx?scid=kb;EN-US;210162&lt;/a&gt;&lt;/p&gt;
&lt;p style="padding-left: 30px;"&gt;925893 - External links may be updated in Excel 2007 when you open a workbook that was last saved in an earlier version of Excel&lt;br /&gt;&lt;a href="http://support.microsoft.com/default.aspx?scid=kb;EN-US;925893"&gt;http://support.microsoft.com/default.aspx?scid=kb;EN-US;925893&lt;/a&gt;&lt;/p&gt;
&lt;p&gt;&lt;strong&gt;Updated Add-ins:&lt;/strong&gt; Check your third party add-in companies to make sure you are using the latest version of the add-in.&amp;nbsp; All too often the code in the add-ins has changed and the newer add-in&lt;br /&gt;will run much better.&lt;/p&gt;
&lt;p&gt;&lt;strong&gt;Formulas:&lt;/strong&gt; Formulas referencing entire columns might display poor performance in .xlsx files.&amp;nbsp; The grid size has grown from 65,536 to 1,048,576 rows and 256 (IV) to 16,384 (XFD) columns.&amp;nbsp; A popular (not a best practice) way to create formulas was to reference entire columns.&lt;/p&gt;
&lt;p style="padding-left: 30px;"&gt;For instance if you have a VLOOKUP that looked like this:&amp;nbsp;&lt;/p&gt;
&lt;p style="padding-left: 30px;"&gt;=VLOOKUP(A1,$D:$M,2,FALSE)&lt;/p&gt;
&lt;p style="padding-left: 30px;"&gt;In Excel 2003 and prior it was referencing 655,560 cells (10 columns x 65,536 rows). With the new bigger grid, this same formula is referencing over 10 million cells.&amp;nbsp; (10 columns x 1,048,576 rows = 10,485,760).&lt;/p&gt;
&lt;p&gt;&lt;strong&gt;Shapes:&lt;/strong&gt; When copy and pasting data from various locations, such as websites and other applications, hidden objects can be copied into the Excel file.&amp;nbsp; These objects can cause performance issues in the preadsheet. &lt;br /&gt;To determine if you have shapes in the file turn on Selection Pane.&amp;nbsp;&lt;/p&gt;
&lt;p&gt;On the Home Ribbon choose, Find and Select, Selection Pane to display a list of all shapes in the worksheet. You can pick and choose to delete the shapes by selecting the shapes and deleting&lt;br /&gt;them.&amp;nbsp; If you want to delete all shapes on the sheet, press Ctrl-G, choose Special, and then choose Objects. This will highlight all shapes and then you can delete them.&lt;/p&gt;
&lt;p&gt;&lt;strong&gt;Defined Names:&lt;/strong&gt; Check for any defined names linking to other workbooks or temporary internet files. Typically these links are unnecessary to the workbook, and slow down the opening of the Excel file.&amp;nbsp; You can use these tools to see hidden defined names that we can&amp;rsquo;t see in the Excel interface.&lt;/p&gt;
&lt;p&gt;&lt;a href="http://www.jkp-ads.com/officemarketplacenm-en.asp"&gt;http://www.jkp-ads.com/officemarketplacenm-en.asp&lt;/a&gt;&lt;/p&gt;
&lt;p&gt;&lt;strong&gt;Styles:&lt;/strong&gt; Old Excel files may collect styles and make the file grow.&amp;nbsp; For more information see &lt;a href="http://support.microsoft.com/kb/213904"&gt;http://support.microsoft.com/kb/213904&lt;/a&gt; and clean out the file of excess styles use the following tool.&lt;/p&gt;
&lt;p style="padding-left: 30px;"&gt;&amp;nbsp;Style Cleaner Tool&lt;/p&gt;
&lt;p&gt;Excess file format cleaner:&amp;nbsp; If files have been formatted by highlighting entire columns the file will grow in size rapidly.&amp;nbsp; We also occasionally see this problem when copying or importing data from web pages or&lt;br /&gt;databases.&amp;nbsp; To clean up excess formatting use the Excess Format cleaner found there &lt;a href="http://xsformatcleaner.codeplex.com/"&gt;http://xsformatcleaner.codeplex.com/&lt;/a&gt; for more information see the following KB&lt;/p&gt;

&lt;p&gt;&lt;a href="http://support.microsoft.com/kb/244435"&gt;http://support.microsoft.com/kb/244435&lt;/a&gt;&lt;/p&gt;
&lt;p&gt;&lt;strong&gt;Personal.xls:&lt;/strong&gt; If you are using a personal macro template located in the XLStart Folder, you will want to make sure that you open it in the latest version of Excel, do a full calculation, and save it as a personal.xlsx. You will only have to do this once.&amp;nbsp; If you don&amp;rsquo;t do this, it calculates each time you open Excel, slowing down the open process.&lt;/p&gt;
&lt;p&gt;&lt;strong&gt;XLSB extension:&lt;/strong&gt;&amp;nbsp; If you have large files that take a long time to open (after their first calculate and save &amp;ndash;number 1 in this list), try saving the file with an .xlsb extension.&amp;nbsp; Saving with this binary format will make the&lt;br /&gt;file smaller and the load times faster.&amp;nbsp; See the following article for more information about the new file formats: &lt;a href="http://blogs.office.com/b/microsoft-excel/archive/2006/07/20/all-about-file-formats.aspx"&gt;http://blogs.office.com/b/microsoft-excel/archive/2006/07/20/all-about-file-formats.aspx&lt;/a&gt;.&lt;/p&gt;
