Hello! I'm trying to install Node Box 3 Version 3.0.51 for Windows on my computer (Windows 10) but I'm getting the following error. First it says: "Class nodebox/client/Application not found." And then when I click "OK" it says: "Failed to launch JVM."
What should I do?

Thank you!

    Here is something that worked for other users getting this error.

    Go to

    Try to install 3.0.50 and see if that works.
    Then try to install 3.0.51 again.

    Please report back with your results. If that doesn't work, maybe Frederik can help.
