    Code 643 when trying to install security updates

    I am trying to install two recent security updates (KB2656370 & KB2656353) and keep getting error code 643 with the updates failing to install.

    I have tried the following fixes to no avail:

    1) Fix MSI software update corruption issues (Microsoft Fixit 50123)

    2) Repair the .NET Framework

    3) Reset Windows Update components and then try updating your computer (Microsoft Fixit 50202 - Default only, I am a bit afraid to try the "Aggressive" option!)

    The above methods were detailed on Error codes

    Any idea what I should do next? Someone somewhere has suggested they should be installed manually - how do I do this?

    Do you have service pack 2 installed? Have you tried the manual download? Have you disabled you antivirus software? Try SFC first System Files - SFC Command
