Windows 7: Microsoft Security Essentials immediately closes after I open it

Microsoft Security Essentials immediately closes after I open it

Good afternoon -

Whenever I try to open Microsoft Security Essentials the GUI briefly appears but then immediately closes, and the system tray icon disappears. If I try to reopen it the same thing happens. If I right click and choose Run As Administrator it opens and stays open. I am running MalwareBytes but have no other AV software running or installed (nor has there ever been). I've tried uninstalling and reinstalling MSE with the same results. I've done full scans with MBAM and MSE and no issues were found.

This is a relatively new PC, only been assembled and running about a week. Not sure what is going on here.

Installed Avast, it runs fine. Also no threats detected. I'm sure it's just some goofy setting or something causing MSE to crash. But if Avast works I'll just use that from now on in place of MSE.
