On this blog and elsewhere, we have received reports of file type associations missing after installing KB2589275.
After installing this update, some users have reported they are unable to open files by double-clicking them, that the file type icons have changed, and that they must go to the application to open files.
We are aware of this issue, and we have been recommending the steps below to correct the problem. We're rolling this up to a blog post to improve visibility and to net in folks who may not understand "File type association" and similar language of software complexity.
You may see this dialog box when trying to double-click to open files:
You may also observe some of the icons related to Office files have changed. Some users have reported the file type icons turn orange, some report the file types appear blank or without the normal Microsoft Office icons.
This happens because the Operating System has lost the association between a file type and the application that it is supposed to open it. This does not change the file, this only affects the relationship between the operating system and the applications associated with the documents. in practical terms, it means that the typical double-click action will fail when trying to open files.
There are several options available to repair this issue. Each will restore Office products to a fully functional state. These are permanent fixes rather than having to revert to opening files inside the applications.
1. Use "Open with..." From any file missing its extension, right click and select "Open With", and then select "Microsoft Office Client Virtualization Handler." This will restore the file type to the application. In some cases, you will see "Microsoft Application Virtualization DDE Launcher." Select this option to restore the file type associations. You can also use the "Choose Default Program..." option, select the same option from that list to permanently restore the file type association to the correct Microsoft Office application.
2. In some cases, you may also need to repair the Office 2010 Starter Edition installation to restore all file types. In this case, visit add / remove programs, select Microsoft Office Starter 2010, and select "Change" from the menu bar.
You will be asked whether you want to repair your existing installation. DO NOT SELECT "Remove all Office user settings related to this product" if you wish to keep your settings on the local computer. Click yes when you are ready. It will take a few minutes to complete, and afterward you should be able to open files from your computer using a double-click action.
If you are unable to open files after performing these operations, please contact Microsoft support at http://support.microsoft.com, or http://answers.microsoft.com/en-us/office.
thank you so very much for the info to fix this:) and it was so easy to do..
is was a great help to me!
My daughter's Presario came with Starter 2010 pre-installed in Q: drive, which is inaccessible.
Using "Microsoft Office Client Virtualization Handler." opens doc or xls files but we have to use that everytime. Bigger problem: if one of these files is attached to an email, I can't bring up this menu to apply "Microsoft Office Client Virtualization Handler.", so cant open attachments.
Repairing Starter does nothing, and as Q: is inaccessible, I cant manually create a association between doc files and the relevant exe files.
Please advise a fix ASAP. One useful answer would be to tell me which update was the culprit, so I can uninstall it.
THANK YOU!! THANK YOU!! I am so happy this fixed my problem. I thought I did something wrong with that last update, glad it is back to normal. I did exactly what it said and it worked!!
So are you going to release an update to fix this mistake - and soon - because your update patch was flawed? It would appear that there are an incredible number of people who have switched on their machines and had a problem, and it's a total cop out merely to say (as you have done above), "The Operating System has lost the association between a file type and the application that it is supposed to open it.". No, I'm sorry but you, as Microsoft, screwed up. I now have horrible orange icons for all my Word and Excel files now, and my saves in Word are prone to crash. And I also can't open any Word or Excel attachments sent to me by email without first saving them to my hard drive. I'm not going to start deleting programs or trying to change associations because why should I? I haven't got the time if the so-called fix doesn't work. So please let me now when your update will available to put everything back as it was.
Has anyone tried system restore?
This fix worked when I initially found this a couple of weeks ago. I had to repeat it a week or so ago and again it worked. But today, the problem recurred and repairing Office Starter did not fix it. When I right click on the document I want to open, the "Microsoft Office Client Virtualization Handler" nor "Microsoft Application Virtualization DDE Launcher" are not options. I also cannot find either of those programs when I browse programs on that screen. Please help.
tried to use the Change function for Microsoft office 2010 starter,as stated above,and I still get that box that says activate when I try to open e-mail with pps. attachments.
Looks like Microsoft is pushing me to BUY office 2013?
I agree - When is the update to correct the problem that you caused? If my son hadn't sent me this blog, I wouldn't even have a clue what had happened. I will try doing it myself but the first method only worked temporarily. So let's hear what Microsoft is going to do!
OK, I fixed it through your method. I hope this won't happen again.
Thank you--this worked! This really had me scared, as I needed to get my work done!
