Repair .Net 3.5 Framework on Windows 7
I have a customer that is running Windows 7 and got a Microsoft Update and now his .Net applications do not work anymore.
How is the best way to repair .Net 3.5 framework on Windows 7?
I found on a blog to try running "%windir%\Microsoft.NET\Fr
They built it into the Windows Features to turn on/off, but when you go there, you cannot uncheck/re-check it... so this is useless. It really stinks when MS pushes out updates and apps start failing.

try download .net 3.5 and re-update the machine:http://www.microsoft.com/downloads/details.aspx?FamilyId=333325fd-ae52-4e35-b531-508d977d32a6&displaylang=en
From the link below, you can download the .NET Cleanup Tool :

It will remove files, directories, registry keys and values and Windows Installer product registration information for the .NET Framework.
After that you may use Microsoft Update on that machine to reinstall .NET framework.

Uninstall 3.5 from Control panel, windows features and reinstall using windows updates including 3.51, which is most likely the culprit update.

Windows 7 does not allow you to uncheck the .Net framework from the Windows Features in the Control Panel... so it cannot be uninstalled/reinstalled from there. The checkbox does not allow you to uncheck it. Try it, it doesn't work. Intuitiveness would say it should, but Microsoft locks out that ability. One of the goofy mysteries of Microsoft. I'm sure there is a reason, but they don't give a work around that is too obvious. If they are going to lock out the ability to uninstall/reinstall it, they should give a tool somewhere to repair it.

Most likely an issue with your system as you should be able to remove it.
Try the cleanup tool above. Have used it with xp but not as yet with win7 but should work well for you.
