I did a version check and I have these versions of 2.0, 3.0, 3.5.

I got a Windows 7 CD from a friend and did a clean install. The 1.1 still refused to be installed, but I did a work around, which work for Windows 7 but not Windows Vista. I created an ISO from the DVD and edit the setup.ini file, removing this line:

"PreRun  = Microsoft .NET Framework 1.1;       MSNET110; Packages\dotnetfx11.exe;    /q"

Proceeded to save the ISO, and the game installed without any hassle.

I hope this helps someone, although I still could not get .NET Framework 1.1 to work.

I do not know whether .NET 1.1 is causing my problems but it seems like it is.

Okay here's the thing, I just got my copy of NBA 2K10 yesterday(spent the whole of yesterday trying to figure out what's wrong with my com, to no avail), so there I was very excited and all, rushing home to install my game. My problem is this: I cant finish the installation of .NET framework 1.1 on my Vista Ultimate SP2, but the game installed like a charm on my other computer running XP SP2. It seems the problem has to do with some "RegSvcs.exe - Common Language Runtime Debugging Services"

The error message: "Application has generated an exception that could not be handled. Process id=0x1294 (4756), thread id=0x164c (5708). Click Ok to terminate and Click Cancel to debug the application. "

I tried to download other .NET 1.1 frameworks from Microsoft, eg. KB867460, KB886903 etc, but they all cant be installed. The error was:

"The upgrade patch cannot be installed by Windows installer service because the program to be upgraded maybe missing, or the upgrade patch may update a different version of the program. Verify that the program to be upgraded exists on your computer and that you have the correct upgrade patch".

How do I get the correct installer if I cannot install this: Microsoft .NET Framework Version 1.1 Redistributable Package

p.s. I tried removing the .NET Frameworks but it didn't seem to work because I did not have 1.1 installed in the first place. (using this tool http://blogs.msdn.com/astebner/archive/2005/04/08/406671.aspx)

Please help.
