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.

    Tried reinstalling SP1 for .Net v1.1 and get a "SL889E.tmp has stopped working" error.  This is a huge waste of my time.

    This doesn't work on Vista.  I get a file not found at step 5 and the files cannot be renamed (Access is Denied).  I am running cmd as Admin.  What a huge waste of my time.

    Earlier than I was expecting!

    So, what do I do now that I've removed all .NET packages and 1.1 won't even install?

    I tried all suggestions on this thread;  most recently I uninstalled all versions (1.1, 2, 3.5, maybe 3 too) via Add/Remove control panel, rebooted, ran the .NET cleanup tool, rebooted.  Now 1.1 installer fails with an illegal memory write (by the Regsvcs.exe app installed by the 1.1 installer).  Another weird thing is that 1.0 appears to be installed (%WINDOWS%\Microsoft.NET\Framework\v1.0.3705 is present & full of files), but doesn't show up in Add/Remove.

    OS is XP Media Center 2002 with SP3.  I can't even remember what the original error was, other than that one of the Oct. 14 .NET updates failed.

    Sometimes things dont work as expected, in my case sometimes I just wait for the next patch round, or the one after and must of the times a revision or a newer patch is release.

    If the patch is not rated as Critical and you other defenses as antivirus and malware removal tools are fully functional and updated then you should be ok... or at least make it without issues till the next round.

    In my case I will continue troubleshooting next week, if I find something then I'll be more than glad to share it.
