fail when trying to instal .NET Framework 3.5

For some reason, my computer refuses to install the:

Microsoft .NET Framework 3.5 Service Pack 1 and .NET Framework 3.5 Family Update (KB951847) x64

It fails every attempt and is listed as an "Important" update. The error found was:

Code 643 Windows Update encountered an unknown error.

What should I do to troubleshoot this problem?

That's quite an undertaking, but I will go through with it and do it. I appreciate your fast reply and I will do my best to follow the suggested procedure for fixing this issue. I will post back whether it works or not.

Re: fail when trying to instal .NET Framework 3.5

Sorry to double post - I know in some forums they request that I edit the previous one before double posting, and some prefer I just add a new post.

Either way, it appears that the tutorial involves operating systems that list .NET Framework versions showing up on the add/remove programs list. Vista Home Premium (my OS) doesn't list .NET on the add/remove program list, so I can't uninstall as directed. Should I skip that step and go directly to the utility that does it for me?
