Microsoft SQL Server 2005 setup, problem detected with .Net Framework 2.0


I just migrated AD DS to a new Windows 2003 SBS R2 server, the server works perfectly but now I need to migrate MS CRM 3.0 to the new server.
To do this I first need to install SQL Server 2005, but everytime I try this I get a nasty error.

It says: Setup has detected a problem with Microsoft .Net Framework installation and cannot proceed.
Microsoft .Net Framework 2.0 is either not installed on this system or corrupt."

When I press ok the setup crashes/stops and windows let me choose between sending or not sending a report.

I tried reparing the .Net framework
I then tried uninstalling and reinstalling it, and applying SP1 to the .NET Framework

I keep getting the same error.

Does anybody has an idea, or does MS has a KB?

Thx guys.

HI techneitsolutions

Please follow steps described in this post



I downloaded the cleanup tool from Aaron Stebner's site, rebooted the server after the uninstall and cleanup.
Reinstalled .NET 2.0 Framework and got exactly the same problem.

What else could be the problem here?
After doing the cleanup and reinstallation the companyweb refused to work.

I just restored to a previous snapshot (thank god for vmware)

What version of IIS are you using ? Have you applied all IIS and Service packs ?

Have you tried the .Net 3.0 version http://msdn.microsoft.com/en-us/windowsvista/bb188202.aspx
