I dont think he was asking anyone for a cd key.

Just does anyone know how he can install it.

Have you got the manual for the game? If you have, take a look on the rear outside cover and see if your cd key is printed there, usually at the bottom.

(It is printed on my manual) as the Serial Number: xxxx-xxxxxx-xxxx-xxxx
For obvious reasons I will not type my number here and consists of four blocks of numbers with dashes between them.

Hope this will be of some help to you.

Good luck
