Interesting results when run in OS Safe Mode -
App opens, but because it is the first time, Office tries to do some configuration, and when it does, I get this error:
Error 1920. Service 'Office Software Protection Platform' (osppsvc) failed to start. Verify that you have sufficient privileges to start system services.
So I cancel that, and it keeps going, trying to install a 64 bit service, then I get this error:
Sorry, office can't start when Windows is in safe mode.
Same thing happens if I try and run the app as administrator.
Tried both Excel and Word.
My OS is legit, as is my copy of Office (both MSDN licensed)

Also, since you can open Office apps in Safe Mode but cannot run them because it is Safe Mode try configuring a "clean boot" and then see if you can open and run Office apps in Normal Mode:
Follow Step 1 to clean boot.
