Well, to do so follow these steps:-

2.Then download a Virtual Image Mounter like Daemon tools,

After that, run the game, by the way, there are alternatives too like a crack. Well, crack is a software that helps you to run a game without CD/DVD, it's piracy by the way therefore I don't use it on original softwares, but you can try it too.
