Windows Update error when installing SP1 code 80070BC9
Hi! I got errors 80070BC9 and C355 when trying to install SP1, security updates KB2478661 and KB2556352 and Internet Explorer 9 with Windows Update. I use Windows 7 Professional x64. I tried to install the updates manually, used the Windows Update Readyness and FixIt tools, and to reinstall the Windows Update agent from the command line as administrator with the /wuforce option. Nothing worked. I uploaded the checksur.log. Can you fix this please?
