Well, making an installer isn't a Swing question. It isn't even a
Java question, it's a Windows question (for you anyway, since you mentioned Windows). So if you were using those terms in your web search, it's maybe no surprise you didn't find anything useful.
Your question is "How do I make an application run automatically when Windows starts?" However since your application has a GUI (or at least I'm assuming it does, since you asked in the Swing forum) you won't be able to start it until the user logs in. Bear that in mind when searching.
You mentioned that you were using "install creator" to make your application installer; it's quite possible that it can make that happen for you automatically at install time, so check through its documentation.
