Question / Help OBS Game Capture not detecting games

[TheAlteredMind]

Hi, Im new to OBS and video recording altogether. Im trying to record footage of an older PC game, Disciples 2 to be specific, and am trying to use OBS to do so. However the Game Capture feature does not detect the game when it is running, even if I run it as administrator. I can get the game to appear in Window Capture mode but never full screened. Help me please?
