    " Double click this file to run it. If that does not work, make sure java is installed. You can also type java -jar tuner.jar on the command line. "

    Install Java: (Oracle changed it's license for their Java today, so go with OpenJDK instead)
    https://jdk.java.net/11/

    Open a command prompt and run the .jar with:
    java -jar tuner.jar

    PS: What is it this simulator is supposed to simulate?
    I did a test run and it presents some loss figures, but there is no option to input any internal resistance values / Q-factors for any components (which is kind of vital for any estimation of loss ;) ).

    I got it working by downloading JRE. It shows loss in a typical T-network tuner as a function of the load R +-jX and frequency. You can set the Qs and tuning ranges of C1, C2 and L.

    Ah, somehow I missed that "Set Up" changed the layout of the window so you could set the Q values.
