Windows Update Error Code 80070643
Got this in my Win7-64 system when applying the Office 2010 SP2 update. The error code suggests some (unspecified) problem with .NET and points to a FixIt routine to fix it.
The FixIt routine did not fix it becuase I got the same error after running it.
The second recommendation is to do a repair on .Net Framework 4 Client Profile. But my system does not have that.
The third recommendation is to repair .Net Framework 1.1 which my system does have. This said to run the .Net Framework Cleanup tool, which I did, but this also failed to complete normally.
It also suggested getting the complete .Net Framework 1, 1.1, and 3.5 installers and running them. That's what I'm about to do.
Well the .Net Framework 1 and 1.1 installers were the same, so I ran one of them and it completed OK. When I tried to run the 3.5 installer nothing happened - no messages, no dialogs, NADA.
So I tried to run the Office 2010 SP2 update again and (of course) it failed with the same error.
So this time I tried running the Windows Update Troubleshooter. This ran OK but said it was not able to fix the Update problem. It did say it fixed several other things though.
I rebooted and tried the Office 2010 SP2 update again. It failed with the same error.
Just for the fun of it I downloaded and installed .Net Framework 4.5 since many of the posts (and there are a lot of them) about this error mention that.
4.5 installed OK and did not ask for a reboot, so I tried the SP2 update again.
It failed with the same error.
I give up.
