Hm... someone had the same problem and he fixed it by removing antivirus program? "
I tried all of the above and none worked for solving my problem.
I has already tried running as Administrator etc... and the 3 methods proposed above - but none of them solved my problem.
In the end I gave up and I went for a completely new install of Windows - and went for Windows Enterprise (a computer tecnician did this for me as!). All the programs / data etc.. were gone and after the install just Windows operating system was on the laptop.
Just after installing I tried running SFC/Scannow (as an administrator from the command prompt of course) and it ran perfectly !! Nothing else had been installed at this point .
Then I thought I'd get my security installed before any viruses infected me - so I installed McAfee.
Then I tried running SFC/Scannow again and gues what ??? It didn't work !! I got the same problem described above.
So, mystery solved (for me at least!!) McAfee was interfering with the SFC/Scannow.
I've now installed all my programs again (Office, etc..) and am using just Microsoft Security Essentials for protection and without McAfee the SFC/Scannow works!
ps. McAfee also seemed to be interferring with installation of another program called ArcGIS (which is why I wanted to run the SFC/Scannow in the first place). I was also able to successfully install that program after removing McAfee." I have nod32 should i disable it or remove it(i don't want to do that :S)?
