As I have discovered, the Animation Shop is somehow a part of the PSP7. The PSP7 is an old application, but Amazon list it with the Animation Shop program as well. I believe you won't have the possibility to use them in the same time in the same application, but separately as two distinctive applications. However, you can create content in Animation Shop and then you can import it in PSP7 as well.
If you want to get PSP7, load Amazon website and then type this searching query: Jasc Paint Shop Pro
