Did it come with the conquerer's expansion (Two ISO's)? If so, The crack is in that folder. You copy the crack across (which lets you get into the game, but requires a cd when you click singleplayer), then you still need the conq's ISO mounted to play the game.
You don't need to crack the original AOE game, just the expansion to play (then have it mounted in the background when you wish to play, otherwise it does the same "No CD" whilst in-game)
