I have Vista Home Premium 32-bit.
After doing a repair install, I had about 30 windows updates to install.
All updates installed successfully except the following:
Microsoft .NET Framework 3.5 Service Pack 1 and .NET Framework 3.5 Family Update (KB951847) x86
I've tried several times to install this update. Each time it goes to Stage 3 100%. But then it says "Update not configured correctly. Reverting changes."
