  • I am having the exact same problem! I have run Microsoft Fix It numerous times trying to resolve the error, but am still unable to install the 2 important updates. The update is: Security Update for Microsoft .NET Framework 1.1 SP1 on Windows XP, Windows Vista, and Windows Server 2008 x86 (KB2656370) The error code is: 643. I am running on Vista and I am tired of seeing it! Please tell us how to resolve this!
