2003, Vista, Windows 7, Server 2008, Server 2008 R2 for x64 (KB2736428)). I keep getting Error Code 643.I am using Windows 7 Ultimate with SP1 64-bit. It was installed clean on my drive by myself . I have had no problems downloading updates till now. This
problem stated on 01/10/13. It went on for a while as the updates were on automatic. I have had several updates of MS security essentials and several optional updates the last of which was today (of the keyboard and mouse). It is only these two that are giving
me a problem.I have researched online to an extensive degree and have found no solution that works, including Microsoft's Mr. Fixit. Any suggestions in which way to go would be appreciated.
