Windows update fails with error code 0x643

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.

    Our site was having the same issue for 100+ computers using Windows Update Server. All were XP or 2003. We resolved it by doing the following via a script:

    1. Uninstall KB976569 - No Reboot Required
    2. Install KB974417 - No Reboot Required
    3. Install KB976569 - No Reboot Required

    Apparently KB974417 needs to be installed before KB976569

    OK!  I just did a clean install of VISTA and got this error - it persists in trying to install this thing.

    Now, just tell me how to uninstall the offending guy.  PLEASE

    Many thanks.  - send the note to *** Email address is removed for privacy ***  - super.

    Please try this as I posted above:

    1. Go here and download the patch to c:\temp: http://www.microsoft.com/downloads/details.aspx?FamilyID=a8f5654f-088e-40b2-bbdb-a83353618b38&displaylang=en
    2. Open a command box and go to c:\temp
    3. Run this command to extract the patch: NDP1.1sp1-KB953297-X86.exe /Xp:c:\temp
    4. Right clicked on the extracted file, S867460.msp, and hit apply

    This has worked for me a number of times.

    One thing about the KB974417 (MS09-061) issue is after re-installing KB976569 over KB974417, KB974417 reportedly disappears from the Add Remove Programs.

    Do I really need the failing update if I have 3.5 installed?  If not I know I can hide the 1.1 update, but how do I fix update manager from thinking I need it if I don't?

    Thanks.
