Thanks for letting me know! I definitely need to address this issue that seems to crop up with deployment. Can I ask if you tried running the DontCollide.jar file directly?

Okay, I'm fairly certain that the JRE being packaged with the game is just not correctly being associated with the .exe and .jar files. I will have to investigate the various settings both in the game engine's sdk and in the Launch4j program to find a process that works for future deployments!
I appreciate you taking the time to respond :)
