Windows update fails with error code 0x643

Are you sure it's not "643", which appears to be common at the moment

When you try to install an update for the .NET Framework 1.0, 1.1, 2.0, 3.0, or 3.5, you may receive Windows Update error code "0x643" or Windows Installer error code "1603"

Please advice the way forward to install it successfully. I have been able to install all other updates successfully.

i was given the error code 463 upon trying to install:

Microsoft .NET Framework 1.1 Service Pack 1.

 and have been recieving this message for about 6 months now, i recently re-tried to run the software and it says i require NetFX, which isn't installed on my computer.

Any ideas? Thanks.

Sorry for the delay in getting back to you all, I have been out for the last few days.

JDHack,

I would give System Restore a shot, if that does not work then we can certainly dive in to see what can be done. If System Restore works, it will save us quite a bit of troubleshooting time.

1. Click START
2. Click 'All Programs'
3. Click 'Accessories'
4. Click 'System Tools'
5. Click 'System Restore'
6. Follow the prompts shown to restore your system back to a date before the issue started. Though System Restore does not target personal data, it's recommended that you back up any data like music, pictures, and documents in case something does go wrong.

Tex222,

Updates to .NET Framework can be picky based upon which versions are installed first and in what order. The original instructions at the top of this thread were meant for XP machines. Have you tried the .NET Framework cleanup utility? I would give that a go and then try to reinstall .NET Framework 3.5 from the stand-alone package.

1. .NET Framework Cleanup Utility:

http://blogs.msdn.com/astebner/attachment/8904493.ashx

2. .NET Framework 3.5 stand-alone installer:

http://www.microsoft.com/downloads/details.aspx?FamilyId=333325FD-AE52-4E35-B531-508D977D32A6&displaylang=en

Also, you mentioned 5 updates for Vista. Do you know which exact updates these are? Are these Framework related or something else?

Thanks!

DaemonRoot,

With the updates you posted above, did that resolve the issue on the rest of your machines? If not, let us know which ones.

Thanks for everyones time and participation,

Thanks!

What a total waste of time.  Were these updates actually tested before being dropped?  I have 5 critical updates for a Vista machine that cannot complete. I have two Windows 2003 Servers that no longer notify me when updates are available via Windows Update.  Something is amiss - where is the love from Microsoft?
