D9 Trondah is right (though a bit too sarcastic). Since the dawn of software, system requirements have been on software boxes albeit usually in obscure places with small type. Besides being Intel-only, you should also be concerned about whether you're system has enough graphics power, hard drive space, processing power and/or the minimum OS. This goes for Windows software as well as Mac.
It's just good sense to always check system requirements prior to buying any software. Unfortunately, that's a lesson your daughter learned the hard way.
