When I start Arma III, charging addons, and check this error:

"Cannot create DX11 device:
Adapter (NVIDIA GeForce GT 420M) Fullscreen
Resolution 1366x768, format R8G8B8A8_UNORM, refresh 60 Hz
Error E_FAIL"

It is not the first time that I install Arma III on this PC

I have attached WinRAR archive with files of the crash. {F25331} {F25332}
