I just fixed this problem. I was getting an error code 0x800040145, I looked in windows/system and windows/system32 and did not find atl.dll. I downloaded atl.dll from Microsoft. I then ran regsvr.exe and installed the dll into the registry, you may not
need to do this step, I did. Then uninstall Microsoft Fix It Center, and then reinstall it.
Worked for me, hope this helps.
