There are a lot of places on the internet where to download Fish Tycoon and each online site has it's own activation code. Our activation code will work only with the trial version downloaded from our site. If you had previously downloaded the game somewhere else, you should delete it and then install our branded version.
The activation code for one platform will not transfer to the other platforms. The handheld and Windows/Mac version have the same genetics, but there are some differences.
