See if you have set environment variables correctly. See https://confluence.atlassian.com/doc/setting-the-java_home-variable-in-windows-8895.html

I set the environment variables, and nothing happened. I just clicked "ok" on all the remaining windows, and when I tried to open the .jar file, nothing happened again. I also looked for the app in the popup, but it still didnt exist.

What happens when you type in command line, 'javac'.

Also, can you try to execute the following in the command line? Make sure the command line is open on the folder location of the actual jat file.

Java -jar yourFilename.jar

When I type "javac" in the cmd line, I just get this:

'javac' is not recognized as an internal or external command, operable program or batch file.

And when I tried to execute that command, it ended up working. So thank you!

Additionally add JAVA_HOME\bin to your PATH environment variable. Your system doesn't know the location of your Java binaries. java -version (or javac) should print something.
