You can install it in many different ways.





Fastest easiest way to do it from scratch is to download a program called winrar. Install it and then extract the iso file. Then the setup.exe should be in it. Just double click and install. you then will need to crack it, which it just copying and pasting everything from the folder called ';reloaded'; or ';vitality'; or ';razor1911'; (depends on which groups release you downloaded) and put everything inside that folder into the folder you installed the game into.
