Need help installing a game

i have mounted the image with alcohol 120% and installed simcity 4 , but when i try to play the game : a message appears and i says that i don't have the cd ...
there is a crack but where do i use it , or where do i copy paste this?
any help is highly appreciated

Stelvio

Edit : tried burning this on CD with alcohol , didn't work, i think i need to do something with the crack
any help?

depends on what kind of crack this is.. most of them you copy/paste the crack in the installation folder. (replacing the original exe )
Didn't the game come with an .nfo file .. just open that with notepad ( right click.. open with.. then choose notepad ).
All the info you need is probably in there
