i downloaded them, wat do i do now? its not executable...there saved as .iso files... wat do i do now ?
You have two choices. I would do both if I were you.
1) You can burn the ISOs to CDs if you have a CD Burner. Just choose the burn image option in whatever software you use.
2) You can try mounting them. When you mount an ISO file your computer will act as though it had an extra CD drive and the ISO was the CD you've inserted into it. A program like
Daemon Tools will allow you to mount the files. Nero also has mounting software included.
Personally I would mount the files, install and try the game (installation is most likely quicker from a mounted ISO than from a real CD drive). If everything worked I'd then burn a copy for backup.
