DX11 feature level 10.0 is required to run the engine

Hi, I’m under a VM, and the DxDiag.txt is here. link text

you see I have DX12 already.
I have not install UE4 yet acturally. I just run some UE4 released binaries , here, Releases · microsoft/AirSim · GitHub

so, how should solve this, please? thanks

I have same when I have broken GPU driver so if you are certain you DirectX is ok then try reinstalling driver to latest version.
