1.16.5 server giving java error after set up of 1.19.2 server

[RowWel]

I had a 1.16.5 server running with no issues, installed a second 1.19.2 server on the computer and it works fine, but since my 1.16.5 is throwing me this(check below) error when launching the run.bat.

any suggestions would be great. I can run the minecraft_server.1.16.5.jar no problem but the forgeserver.jar wont open, I am assuming it is running this same error in the backend

Minecraft 1.16.5 requires Java 8 while 1.19.2 requires Java 17. They both can't use the same `java` command as one will always be ahead of the other on the PATH. To remedy this, you would need to use the absolute location of the `java` command for each version rather than the one currently on the PATH.
