Your image isn't showing, so can't see exactly what you're talking about. But, if 7H can't find the game, it means something is wrong with your registry. Perhaps you installed multiple copies in different folders at some point. You should be able to just go into 7H>Settings>General Settings and point to the correct location. Even if you don't have an ff7.exe in the correct folder, select your ff7_en.exe and 7H will fix it for you.
