original title: Error 80041002 when installing service pack 1
I have a windows 2008 R2 x64 which im trying to install service pack 1(KB976932) on to. originally the update came from a WSUS server on the network, i deleted the cached update from the server having the issue and redownloaded from the WSUS server i still
could not install. i have also tried to install from a downloaded copy of service pack 1 from the internet.
i tried all the above steps with my Anti Virus switched off. i have also tried running the systems update readiness tool which didnt flag any errors up.
after trying all of the above i get a 80041002 error from within Windows Update program. this also generates two error messages in event viewer from within the system pane:
1. event 20:
Installation Failure: Windows failed to install the following update with error 0x80070643: Windows Server 2008 R2 Service Pack 1 for x64-based Systems (KB976932).
2. event 8:
Service Pack installation failed with error code 0x80041002.
Any advice or help would be greafully received.
