Installation of SQL Server 2008 fails due to “previous” release of VS 2008

I am trying to install SQL 2008 and it gets to the beginning of the installation and somehow “detects” that there is a previous release of VS 2008 and it refuses to go any further. I looked at my installation of VS 2008 and I have applied SP1:

first uninstall dotnet framework 3.5 and try installing SQL Server 2008. After the sucessful installation of SQL Server 2008, re install .NET framework 3.5 -Madhan Well, the SQL Server installation installs the .NET Frame 3.5 SP1 already. I think that uninstalling the .NET Framework is a good step though.

Now I am trying it on Windows 7 and I am first greeted with a message: “This program has known compatibility issues….After SQL Server Setup completes, you must apply SQL Server 2008 Service Pack 1 (SP1) or a later service pack before you run SQL Server 2008 on this version of Windows”. I then click on “Run Program” which I interpret as “do it anyway”. The I get a dialog box indicating that SQL is processing. Then I get a Window entitled “SQL Server Installation Guide” with no indication of processing there after.Kevin
