Well there is a whole heap of acer gamezone keys but you may need to specify one anyway here is a way to get Acer GameZone Games on Vista:

Got to Program Files and find the Acer Gamezone folder look for your game and click on it. Note will only work on Vista not XP or windows 7 still you can try it out. If you don't have vista download virtual machine and install on there.

I think you can get it at Gamezone or on other downloading sites
