Install WSS3.0 and MOSS 2007 on Windows 2008 Server R2

Installing SharePoint (either WSS 3.0 or MOSS 2007) on a Windows Server 2008 R2 is not just a 'next-next-finish' action.
At least, I tried it with MOSS 2007 with SP1. It will not work!

You will get the following error message:

Title: Program Compatibility Assistant
Message: No solutions found for Office SharePoint Server 2007 - Please read Microsoft Knowledge Base article: 962935

Don't try to find this KB article (it's here). It doesn't have anything to do with this particular problem.

The work-around for this problem is as follows:

1. Copy the setup folder of WSS3.0 or MOSS 2007 to the local drive of the server, e.g. C:\Moss_Install
2. Delete all content in the sub folder "updates"
3. Download WSS3.0 SP2 (here) and MOSS 2007 SP2 (here)
4. Open a command prompt and navigate to the folder where you put the both SP2 files
5. Extract WSS 3.0 SP2 and MOSS 2007 SP2 using the command prompt:
   [filename] /extract:[path to copied setup folder step 1]\Updates /quiet
   Example:
   officeserver2007sp2-kb953334-x64-fullfile-en-us.exe /extract:c:\Moss_Install\Updates
   The SharePoint installation program will automatically read this folder to apply the patches.
6. Optional: some people mention to delete the wsssetup.dll file. I didn't for the MOSS setup. It just works leaving this file.
7. Start the setup.exe in the copied setup folder and you are on your way.
