im using windows 7 that came along with DX 11 and I installed the game "devil may cry 4" in my pc , but this game is for Dx 9 or 10, so when i try to install dx9 or 10, my computer screen just went black and nothing happen that means im not able to install dx9 or 10. I would be very happy if anyone can help me with this problem.
