We generally do not support older versions; however, since yours seems to be an issue with java version, I will make an exception. 1.12.2 requires Java 8 to run. It seems like you are running with a later version of java.

i installed java 8 after i read something online about it, how do i make sure it opens with java 8 and not java 19? since that seems to be the problem

Either specify the path of the application to be the java 8 executable or make sure Java 8 shows up on the PATH environment variable before java 19. Probably should set JAVA_HOME to the java 8 location as well.
