Majalis, I cross-referenced the engine you are using for the game and the issue appears to be that the engine requires OpenGL 2.0 support. I do not think there is anything you can do about this particular issue. A lot of older computers that could run the game will not be able to because of how slipshod OpenGL support was ~8-10 years ago. One can assume any computer made during the early Win 7 era and newer should not have an issue, but computers made during the XP/Vista era may only support OpenGL 1.4 or 1.5, preventing those rigs from running the game despite meeting all other system requirements.
