If you're a little lost when it comes to this subject, don't worry; the program includes three templates with the source codes for several different installation packets: basic, advanced and multiple.
You can edit these templates and search how to generate an installer using only this popular programming meta-language.
The commercial version includes a graphic interface that replaces the source code editor, but that doesn't mean that you won't be able to general an installation packet by hand.
Lastly, save the result and put the project together. Now you have an installer for your program!
