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

Thanks for the help. Got it figured out.
