MoH Airborne GPU not supported message

So, I see that the game says its not compatible with Win64 systems, but I don't have any way to modify those setup properties (that I can find) and the only results I've been able to find online for fixes to this game are either for the old Steam release of the game, or for the Mac version from five years ago. Neither apply here since they rely on an older build of the Nvidia app to provide a solution, so if there's anyone that has a more up-to-date method that applies here, that'd be great.
