I think this is an unreal game (sorry I do not have it and not a fan of the MK series). So find the real .exe in the folders (not the one at the root), then put the x64 version for xinput1_3.dll and the x360kb.ini in the same folder. Launch that .exe directly. Works for me on all Unreal games. You might have to remove the keys assigned to the dpad if not in the menus when you go up or down it goes down by 2 instead of 1.
