On my Windows 7 Microsoft. NET Version 2.0 is installed but isn't...

I recently updated to Windows 7 and now that I have everytime I log in and when I try to use certain programs it tells me I need Microsoft. NET Version 2.0 so I downloaded it the only version that worked was the 64 bit version (which makes sense because my computer is 64 bit) and the program tells me its included in the OS. What do I do? If I have .NET Version 2.0 how do I turn it on? Please someone give me a solution!

Hi matagy,

 

Welcome to Microsoft Answers.


For Windows 7, .NET Framework 3.5 with SP1 is shipped with it as one of OS component.
For .NET Framework 3.5 with SP1, it includes .NET 2.0 with SP2 and .NET 3.0 with SP2 as prerequisite.
This means, you have the .NET Framework 2.0 SP2, 3.0 SP2 and 3.5 SP1 plus a few post 3.5 SP1 bug fixes on Windows 7. They are OS components. .NET 3.0 SP2 and 3.5 SP1 can be added or removed via the Programs and Features control panel.
Thus, we don't need to manually install them. That's why you received the error message when you tried to install .NET 2.0 on Windows 7.

As for your concern, please use Verification Tool to verify .Net Framework 2.0. If .Net Framework 2.0 cannot be verified on your computer, you can try to follow the steps mentioned in the following blog to repair the .NET Framework 2.0 on Windows 7.
See:
http://blogs.msdn.com/astebner/archive/2007/03/26/how-to-repair-the-net-framework-2-0-and-3-0-on-windows-vista.aspx (also apply for Windows 7)
If .NET Framework 2.0 can be verified, we can isolate the possible cause of corrupted .NET Framework 2.0.

Hope this helps. Let us know the results.
