I didn’t understood you well so i’ll give you 2 options that i understood that this your the problem:
1. If you installed the game properly and all you need is a crack so you can play, So, Go to http://www.gamecopyworld.com, click on one of the mirrors that are online (most of them are online) and then go down and click ENTER. Wait until the page will load and when it’s finished you’ll see in the right side of the screen a button called “Game Index”. Click on this button and then search for the game (you have up the abc letters for quick skipping between the letters).
Now download the crack for your version of game, and extract it to the directory where you installed the game. He needs to ask you if you want to replace the original with the one you downloaded (If not, search in the directory where you installed the game a file named like the file that is zipped in the file you downloaded). Click yes. Enjoy playing
2. If you can’t even install it because you need a serial code here is a solution:
If you downloaded the game as a zipped file, (mostly .tar file but it can also be .rar file),
the zipped file should include an .nfo file. Open the .nfo file with notepad. The .nfo file is supposed to include installation instructions. Under this the serial should be written. If not, a key generator should be included in the crack directory on the cd. Read the installation instructions carefully and do what it says.
If you downloaded the game from kazaa or other file sharing software just search for the nfo file and download it and then follow the istallation instructions that’s supposed to be written in.
Hope I helped
