I'm having an issue with an update that has been trying to install for a few days now, and it just won't install. The update is called "Security Update for Microsoft .NET Framework, Version 1.1 Service Pack 1 (KB929729)" It never completes installing, and I get error code: 642, but the Windows Help link doesn't find anything that relates to the issue. I've tried finding a way to keep this update from popping up since it's not installing correctly, but can't find a way to do that either, any help would be greatly appreciated.
