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.

    Sun Yuyan,

    I'm not sure how I can help. I no longer have access to a Windows machine to do any testing.

    Frederick, do you have any ideas?

    Are there any Windows 10 users out there who can confirm that 3.0.51 works for them?

    I can test tonight on a brand new Windows machine.

    I just tried this on a brand new Windows 10 (64 bit) machine, had no issues downloading / installing / running Windows.

    Not sure if you could try this trick to get it running (or at least to get more descriptive erors):
