Microsoft Security Essentials will not install - 0x80070645
hi, can any one suggest why Microsoft Security Essentials will not install, I have removed all other av programs with revo uninstaller and cant find any leftovers at all.
The installer goes through initial stages,but then pops up a error message 0x80070645.

See KB2635095 and run the Fix It mentioned there and then try again.
This should help!
