I want my application to be usable on all computers, but it only works on mine.
Apparently this has something to do with it checking for versions of Java relative to the computer(???).

I'm either a fucking noob at Java, and has no life to not be using any good tools (a.k.a. primitive, ancient, and lesser-skilled), or there aren't that many tools for it (either way, I should understand why it's not working, if I wanna work in Java).
What I want to do is convert my .jae which works on only my computer to a .jar (yes, another .jar, so that it's still platform-independent) that will work on ALL computers that have a JRE (native or manually installed).

Of course I'm too naive to understand any of this (since I'm so homosapien-like, I use CMDPrompt to compile and view errors (that VSCode didn't warn me of)), so, do any of you know of any tools I could use to accomplish my overall goal?

Thanks in advance! It means a lot to me.
Cheers!
