I have downloaded the recent Microsoft updates and all but one installed successfully.  The failing update was:  Microsoft .NET Framework 1.1 Service Pack 1 Security Update for Windows 2000, Windows XP, Windows Vista, Windows Server 2008, Windows 7, and Windows Server 2008 R2 (KB953297);

with an error code of  0x643.

We tried several times to install it and it keeps failing.  It was originally the 3rd update in the list to install.  After failing the first time, it was the only one we were trying to install.  We tried it after the restart required for the other updates.

    Hi taki99

    The solution I used was :

    After spending an entire day on just one PC running XP Pro SP3, I finally solved my problem as follows:

    1. Used Control Panel-Add/Remove programs to remove those .NET Framework versions which would uninstall.

    1. Used Windows Installer CleanUp Utility (http://support.microsoft.com/kb/290301) to remove remaining versions.
    2. Used Aaron Stebner's tool (http://blogs.msdn.com/astebner/archive/2006/05/30/611355.aspx) to remove remaining vestiges of .NET framework.
    3. Tried to install all previously present .NET Framework versions, using the links on http://support.microsoft.com/kb/923100. I got as far as 2.0 SP1. 3.0 wouldn't install due to "DepCheck indicates Windows Communication Foundation is not installed" (http://social.msdn.microsoft.com/forums/en-US/netfxsetup/thread/acfacc44-c3c8-48ad-94df-f5d2d1f10bb1/). The workarounds on that page didn't help me.
    4. Ran Windows Update. Much to my pleasant surprise, this installed 2.0 SP2, 3.0 SP2, and 3.5 SP1.

    It shouldn't have to be this hard!

    Well provided by davelasker !!

    Hope this helps.
