I created a jar file at the end of my project. I build it with IntelliJ and inside it, the file runs smoothly. But the moment I try and execute it from the Desktop, I get nothing. Zero response. If I try to open it from the command line I get this message:
Error: JavaFX runtime components are missing, and are required to run this application
So I figured - I need to install separate JRE. Originally I thought it came along with my JDK but apparently it did not. So I installed JRE in the same Java folder I have my JDK. I run the program again, and now I get this error...
Error: A JNI error has occurred, please check your installation and try again
Exception in thread "main" java.lang.UnsupportedClassVersionError: com/javafx/main/Main has been compiled by a more recent version of the Java Runtime (class file version 57.0), this version of the Java Runtime only recognizes class file versions up to 52.0

I do not understand why it has a problem with my installation. The file was downloaded from Oracle, I didn't even change default destination folder.
I am currently using JDK 13.0.1 and JRE 1.8.0_231
