I am unable to install Windows 7 Service Pack 1 on a desktop PC. I get this error message:
Installation was not successful
"The referenced assembly could not be found"
I have tried running a couple utilities from Microsoft:
* Automatically reset Windows Update components
* System Update Readiness Tool for Windows 7 (KB947821) [August 2011]
* sfc.exe /scannow
I also updated the driver for the graphics card.
Any help would be greatly appreciated.
