Preliminary soft- and hardware requirements and prerequisites for SharePoint 2010 beta installation.
We've seen some confusion in the newsgroups and elsewhere on the versions and editions of Windows that SharePoint 2010 will run on. This post is meant to clarify some of the most common questions we have seen.
SharePoint 2010 will support only 64-bit (x64) versions of Windows Server 2008 SP2 and Windows Server 2008 R2. SharePoint will not install at all on 32 bit Windows, or any earlier version of Windows such as Windows Server 2000 or Windows Server 2003.
SharePoint is not supported on 'Server Core' installations of Windows Server 2008 and R2. The Server Core installations of Windows server do not contain some of the components required for SharePoint to be configured or run.
To see a full list of all supported systems, please visit our "SharePoint Team Blog" for more: http://blogs.msdn.com/sharepoint/archive/2010/01/22/operating-system-requirements-of-sharepoint-2010.aspx
Server 2008 Note!
You must download the above mentioned updates for Windows Server 2008/2008 R2 before you run SPS2010 Setup! If you don't have this fix installed, you will get "Unrecognized attribute 'allowInsecureTransport'" error in ULS log and most of the service applications will not run properly. Please note that the 2008 fix also applies to Vista, while the 2008 R2 fix also applies to Windows 7.
Web Server Editions are not supported. Windows Server Foundation edition is not supported either. You can also install SharePoint 2010 on Windows 7 and Vista, however additional steps would be required as pre-requisite installer does not work currently on client OS. Windows 7 N and KN would not work due to an installer bug. Please also note Office Web Application needs to follow the same edit of config.xml to be installed on client OS.
SQL Note! When you use a separate SQL Server on a Server 2008 operating system, please bear in mind that you may add a rule to the advanced firewall and allow minimum port 1433 for remote access. Otherwise the Configuration wizard is not able to finish the setup due to failed creation of the config database. For SQL Server on Windows 2008/R2, you can use the script in KB 968872 to open all necessary ports.
