Game Crashes on Startup with "Untrusted System File" error


Whenever I try to start the game it appears as though absolutely nothing happens and then 2 minutes later I will get this pop up:

I have already tried:

>Reinstalling EAC

>Uninstalling and Reinstalling DBD

>Verifying integrity of game files

None of which have had any success. Really not sure where else to go from here.

    Open GeForce Experience software, go to drivers tab and select reinstall driver. When you see an option called "Clean Install" select that during the install process. Also make sure to select express install instead of manual so it installs PhysX for you. But if you select manual make sure to also install PhysX.

    If you don't have GeForce Experience install that since it makes updating graphics drivers very easy and notifies you of new drivers automatically.

    If you haven't installed latest graphics drivers then that should fix PhysX not functioning.
