1. Install the game. For serials, visit (for example) www.serials.ws
2. Copy the 'Sims2.exe' file from the Crack directory to the 'The Sims 2\TSBin' directory (default: C:\Program Files\EA Games\The Sims 2\TSBin)
3. Now you can play the game with CD1 or the DVD in your disk-drive. If you want to play the game "without" a cd, you can use the mini-image file in the 'Mini-image' directory. You can mount the file with an up-to-date version of Alcohol 120% or Deamon Tools. The image is only 1,5MB of size and contains just the security files.
