This torrent contains a 7z file which contains a copy of this game's DVD in a .mdf format.

How to install/run game:

Simply mount the ISO using your virtual CD/DVD mounting software of choice, I personally like WinCDEmu found here: http://wincdemu.sysprogs.org/ but pretty much any virtual CD/DVD mounting software should work.

Then install the game by launching it's SETUP.exe file found in the mounted CD, and then click the Install button and follow the install wizard like you would with any standard windows software.

The game does not require the CD to be mounted to play so as soon as you have installed the game you can safely eject/unmount the game CD and not worry about it again.
