I'm seeing the same error in Windows 7 Professional x64. System keeps trying to do restore and does manage to recover somewhat. I discovered this Event Viewer error due to system having issues, an occasional blue screen. I did CHKDSK and have seen no issues. Was hoping the Event Viewer would shed some light...but that's when I discovered MMC 3.0 error. Error message in Event Viewer says "The snap-in might not have been installed correctly". Please advise. MMC could not create the snap-in. Name: Event Viewer

Please start the command prompt (cmd.exe) with admin rights [1] and run sfc [2]: sfc.exe /scannow Is it able to find and repair broken files (create the txt file shown under [2] and look if all files are restored)? best regards André [1] http://windows.microsoft.com/en-US/windows7/How-do-I-run-an-application-once-with-a-full-administrator-access-token [2] http://support.microsoft.com/kb/929833"A programmer is just a tool which converts caffeine into code" Want to install RSAT on Windows 7 Sp1?

Well that didn't work Andre...sfc.exe didn't find any issues. Problem still persists.Jim Pruitt

Hi, You still encounter the same situation when you finish performing the SFC command. This may be caused by the files stored in Winsxs folder is also damaged. Find if there is any file called “mmc.exe.config” and delete if it exists for a test. If it does not help, the easiest way to fix the issue is to perform an in-place install. Hope this helps.Please remember to click Mark as Answer on the post that helps you, and to click Unmark as Answer if a marked post does not actually answer your question.
