I'm not aware of his previous post, so I hope me answering this doesn't land me a warning from the admins. After you launch Crossover, if you go up to the toolbar up top, and look for "Run command" or "run program" I forget which, you can choose or drag the exe you want to launch, and see if it does. Some exes don't work with Crossover however, in which case you'll have to use a virtual machine or bootcamp.
