Hi,How are you attempting to launch the game? Via the GeForce Experience App or the Windows Start Menu? Did you use Windows to move the install to another drive, or did you move the files manually? Looking at my NVidea GeForce app, Windows seems to think Gears ofWar 4 is still located in the C drive under the path:C:\Program Files\WindowsApps\Microsoft.SpartaUWP_14.3.0.2_圆4_8wekyb3d8bbwe\The Game is definitly located within my D drive, I have uninstalled and reinstalled 5-6 times, all drivers are up to date and so is my version of Windows 10 :)
Now whenever I launch the game I receive a black screen after the gears logo fades out. I moved Gears of War 4 from my C drive to my D drive as the game became too large with the updates.
