Installation Failure: Windows failed to install the following update with error 0x80070643: Microsoft .NET Framework 3.5 Family Update (KB959209) x64.

Hello Experts,

I am having an issue with one of my windows server 2003 64 Bit system. The system has one of the patch pending since from long time .

Patch - Microsoft .NET Framework 3.5 Family Update (KB959209) x64.

Now,

When I try to install it on the system it is throwing me the below error message

"Installation Failure: Windows failed to install the following update with error 0x80070643: Microsoft .NET Framework 3.5 Family Update (KB959209) x64."

I am sure this is not a issue from WSUS side , It is a issue with .net or MSI instller here.

Can anyone help me in resolving this issue?

Thanks,

This issue may occur if the MSI software update registration has become corrupted, or if the .NET installation on the computer has become corrupted.

could be that WSUS dodwnload the corrupted Net setup.

will suggest you please run windows update on that system and then select custom and choose ,Net setup

it could be chance that if your retry this installation from wsus will create issue on server.
