    @vliwei3

    Thank you for reaching out to us.

    I checked the source code page on GitHub.

    Note

    : Because the package was built using JDK 1.8. which conveniently packages the JavaFx package, user must ensure they install Java 8 runtime.

    Hi @Jirapongse, we have pretty much the same problem, but it seems like the root of the crash lies in the Java 8 runtime itself

    $ java -jar .\SpeedGuide.jar
Error: JavaFX has been removed from JDK 8.
Visit https://www.oracle.com/javase/javafx for more information.
Error: Could not find or load main class com.lseg.ema.example.gui.SpeedGuide

    Any suggestions?

    Thanks in advance.

    The SpeedGuide uses the JavaFX.

    I checked and found that the JavaFX may be removed from the new versions of JDK 1.8.

    I tested it with the JDK 1.8.0_333 and it can run the SpeedGuide properly.
