PC install disk problem

I currently just found my final fantasy 7 disks for my pc! i got really excited and then i reailzed oh damnit... i dont have the install disk... is there a way that i could download the install disk off of a site or a file sharing program or somesort? i would really apprecate the help ty :)

Yea, I just downloaded it off of Ares, but I can't play it because you never get a chance to enter your cd key since it installs itself.
