    Trying to run updates & keep getting this error: code 643 or WindowsUpdate_00000643 as it states.
    I cannot find any reference to it on MS sites. What does it mean & what do I need to do to install that update? The update (KB929729) has to do with .Net

    Dan, had the same problem until this afternoon. There was a post on 7/23 by
    Andrew McLaren that solved the whole thing for me in about half an hour
    (would have been quicker but my wife had other things for me to do at the
    same time). Here is the solution from that post:

    "Thanks and kudos to Chris Rowat, who first provided this solution over in
    the MSDN forums :-

    1) Download and run the Windows Installer Cleanup Utility. Use it to remove
    the .NET Framework 1.1 from the machine.

    Windows Installer Cleanup Utility

    2) Download .NET Framework 1.1 from the Microsoft website (don't download
    via Windows Update), and save it to your hard disk (file name dotnetfx.exe).

    ..NET Framework 1.1

    3) Download .NET Framework 1.1 Service Pack 1, and save it to your hard disk
    (file name NDP1.1sp1-KB867460-X86.exe)

    ..NET Framework 1.1 Service Pack 1

    4) Run the downloaded dotnetfx.exe to install .NET Framework 1.1.

    5) Reboot your machine.

    6) Run NDP1.1sp1-KB867460-X86.exe to install .NET Framework 1.1 SP1.

    7) Reboot your computer again.

    8) Now run Windows Update again, to install post SP1 hotfixes.

    Not all the reboots maybe necessary, but ... better safe than sorry.

    Caveat: I have not used this myself (I never got the 643 error). But many
    folks in MSDN forums have confirmed this procedure has fixed the "643" error
    for them. There may be other solutions, too.

    Hope this helps,

    Hope this works for you, assuming you haven't found a solution as of yet.

    What a lame reply. If you aren't going to be of help, just stick to the
    trash threads and keep your nose out of the problem threads. People are
    asking for help because they need the help, not because they're looking to
    change OS.

    Get a life!!!
