All Pro Toolkit stuff is on the installation files of you Creo / Wildfire installation. You can choose to install it with your installation and then find it in the folder
so you need to look at your installation path.
If you have find that stuff you can check the examples and need to know a little bit about C programming. If programming is not your main interrest you should take a look at .Web/link or J-Link too, because there much easier to learn for a programming newbie.
