Running Windows 10, I would like to play FNV on Windows 7 Compatibility Mode. But when I launch "FalloutNV.exe", this code error appears: 0xc000001d. Before reinstalling the game (my internet is very slow), I want to be sure that you don't have any idea to resolve this problem.

I have the same problem @Prosp3ro and I don`t know how to solve this problem. I intend to go back to windows 7 but now I`m determined like never before because I have too much problems with windows 10 in many games, not only with FNV.

@Lôke-khan K.B. I found out that it is an ENB related problem, but I don't know if it would happen in Windows 7. Yes, W10 is not ideal, especially for 32bit games like FNV.
