Hello, I am trying to download Heroes 3 on my Mac, however, it doesn't even let me download the game. I tired and failed to figure out how to use winebottler but it didn't work because I didn't even have options on opening to the game with the bottler. I'm very confused and doesn't even know what to ask for help with. please help

you do understand that an exe file is only for Windows

i'd walk you over it but the kind of Mac i.e, system you have matters a LOT
