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.

    Download the .Net cleanup tool from the below link

     Run the tool to uninstall the  .Net completely, restart the machine.

    Then Run the updates again, which will complete successfully....
