Could Not Create Java Virtual Machine

I am new to Openremote and followed the setup video on youtube. Everything went well until I actually tried to start the controller. I’ve retraced the setup steps and still cannot get it to work. Am I missing a steup? Is there something I need to do in the designer before trying to run the controller? Thanks in advance.

What version of java are you using?
java -version

I am using java version 14

This is the problem. OR2.5 requires Java 8, older versions even Java 6. You can either downgrade Java or use Docker (preferred). See https://github.com/openremote/Controller

Thanks for the help. Got it figured out.
