So yeah I'm getting the old MSI could not be accessed crap whenever I try to install *any* MSI file
I've tried all the fixes involving the registry and putting an _ infront of the key but the problem there is I *dont* have that registry key there all thats there is default
I've tried manually starting the Windows Installer service but it says "access denied"
and to top it all off I can't play Overlord 2 because I can't update my Physx drivers
due to it!
