D3D11 not working on laptop with D3d11 capable video card gtx 850m

Hi all, i tried to install D3D11 to use highres textures, but i have issues:

I get the following error when launching the game:
The procedure entry point ?Placeholder@URENDERDEVICE@@UAEXXZ could not be located in the dynamic link library D3D11Drv.dll.

It seems unreal can t use the discrete graphic on my laptop (GTX850m and HD4600), even when putting the preference to use the discrete nvidia on the control panel. The game won 't start unless i put startfullscreen=false, in this case i get the error and the game starts but with texture corruption and very clear artifacts, any advice?

My error, the gog setup was identified as 227i but i checked in game and the version is 226, installing 227i solved the problem, thanks for the great work!
