Ultra Animation \ Games Inside Inno Setup
 

Using this script you can load EXE files into inno setup, there you can load exe animation files (for example created by DP Animation Maker) inside the setup.

Also, you can load small games into the setup, so the user will play them while installing the game:)

Out there, there are several dll libraries that can make a water / fire effect to use inside the inno setup and so on.
But using this trick, you can create wonderful animations more than a water / fire effect (also with sound) using DP animation maker and then load them into setup:)
