Windows update .NET Framework 4 error

[mierau]

Hi,

I can't install .Microsoft .NET Framework 4 Client Profile for Windows 7 x64-based Systems (KB982670) (using Windows Update). Please see below the details:

Installation date: ‎9/‎4/‎2012 9:57 AM

Installation status: Failed

Error details: Code 643

Update type: Recommended

The Microsoft .NET Framework 4 Client Profile provides a subset of features from the .NET Framework 4. The Client Profile is designed to run client applications and to enable the fastest possible deployment for Windows Presentation Foundation (WPF) and Windows Forms technology.

I tried to install the standalone version, but I get the same error.

The problem is a few months old. I messed up smth. trying to install a program sent by one client. I couldn't solve it using the restore option at that time either.

Any suggestion would be much appreciated.

Thanks in advance!

Try running the Net framework cleanup tool.

Download it, run the tool, remove .net Framework 4.0 and then attempt to reinstall. If not successful you can always remove ALL .net framework and reinstall them.

Hi there,

Thanks for your reply.

Already been there, tried that...if it were that simple It seems my problem is "deeper".

Have you checked the KB# and seen if it is already installed? Sometimes this can happen where windows updates gets confused. it says you need update KB******* but then you check your update history and sure enough it's already there. In this case, you uninstall the update and reinstall it. This should refresh it and show the update installed and not as required to install.

You could try the MSDN forums. There are MS employees and MVPs who read those forums and should be able to help out.

make sure you note the right .net frameworks because a lot of programs use them and can become corrupt if .net is uninstalled or will not function if it is reinstalled.
