Reboot in safe mode and go to C:\Windows\System32. Copy all files included in the zip package (mfc100.dll, mfc100u.dll, msvcr100.dll, msvcp100.dll and msvcr100_clr0400.dll) to C:\Windows\System32 replacing the current ones. After that reboot in normal mode.
If all the solutions above haven't worked, consider backing up data and performing a clean install of Windows.
