SharePoint install blocked due to compatibility issues on Windows 2008 R2

You'll get this message if you try to install SharePoint on a fresh install of Windows 2008 R2. As of this posting both MOSS packed with sp2 and the Kbase doc referenced in the message (KB962935) are not available. The workaround, however, is very simple.

"This program is blocked due to compatibility issues"

The problem in a nutshell is any MOSS install package be it the RTM or MOSS w/sp1 don't have the latest updates in it. Because you've presumably updated your Windows 2008 and 2008 SQL Server with the latest patches, you can't install MOSS unless you repackage it with the SP2 update files. The instructions below explain how to, in a sense, repackage your MOSS install bundle with the latest updates.

1. Create a temp directory... C:\Temp2

2. Download the 2007 Microsoft Office Servers Service Pack 2 (SP2)

3. Start > Run and paste in the line below
C:\Temp2\officeserver2007sp2-kb953334-x64-fullfile-en-us.exe /extract:C:\Temp2\

4. Go to your SharePoint install and delete all the files in the "Updates" folder

5. Copy all the extracted files from step 3 to the Updates folder.

6. Install!
