Use the Keygen during the installation. After you install the game, use the Crack which is a NoCD mod and DOES NOT need to be replaced after every update, but requires you to use a shortcut to TS3W.exe in C:\Program Files (x86)\Electronic Arts\The Sims 3\Game\Bin. You MUST launch using TS3W.exe and you will get an error if you use the launcher.
