I have been trying to install the same update for over a week. It involves Microsoft NET Framework 2.0 Service Pack. It appears to be downloading from Microsoft Update but never installs. Furthermore it freezes the whole system, which requires rebooting. The Failure Code seems to be Ox800706BE. A Google search on that came up with PRC_S_CALL_FAILED, but I have no idea what this means. Can anyone solve this problem? Layman's terms please. Many thanks.
