Problems with playing a game

More info needed. What is the game? Is it for the Mac or PC? What is your computer and it's specs

 

If I might offer my own interpretation of the issue...from your brief description it sounds like the install disc for the game isn't even reading? Have you checked the disc for any scuffs/scratches? Do DVD movies, install discs for other applications work in the drive?

 

Reading that makes me think that there is something wrong with the optical media (CD, DVD) or the optical drive in your Mac.
If all other CD's and DVD's work fine, then try to replace your purchased CD/DVD of the game.

But, it would make it a lot easier for us if you could post more info:
1) Which game?
2) Which Mac?
3) Mac OS X or Windows (Boot Camp)?
4) Better description of problem...
