Hi, the d3d9.dll file should be placed in the folder you put the game, just beside the FragmentsOfEuclid.exe file. For the command, you can try downloading this file I made for you : http://lezanu.fr/FragmentsOfEuclid/ForceD3D.bat and put it at the same place (beside FragmentsOfEuclid.exe) and double-click on it. This should launch the game and force using D3D9. But I don't know if it will work and if it don't, I'm out of ideas.
