Greenfoot Technical Support

We have a dedicated email address for technical problems. Please note it is only for problems with the installation or operation of Greenfoot itself, not for help with programming problems (use our discussions area instead).

Before emailing for support you should do a web search to see if there is a solution available.

You should also make sure you are running the latest version of Greenfoot with the latest Java update. On Windows you may have to run the "select VM" utility (from the Start menu) to choose the right JDK version.

When sending a support request you should:

  • Specify your operating system (Windows? Mac? Linux? something else?) and version
  • Specify which version of Greenfoot you are using
  • Be specific - give as much information about the problem as possible. Include information about what you do to cause the problem, and the exact error message (if any) that you get.
  • Include the debug log - the file called "greenfoot-debuglog.txt", whose location should be displayed in the "About Greenfoot" dialog which you can access from the Greenfoot menu. We need this to try and sort out your problem! Without it, you'll most likely just get an email back asking for it.

    Important! Always include the debug log. If you cannot see the "About Greenfoot" dialog for some reason, try and do a search for "greenfoot-debuglog.txt". If you still can't find it, please mention this in your email.

    Note: unfortunately the "About Greenfoot" dialog doesn't show the correct location of the debug log file in Greenfoot 2.3.0 - this will be corrected in the next Greenfoot release. For Windows, look in "your-profile-folder\greenfoot". For Mac OS, look in "/Users/your-username/Library/Preferences/org.greenfoot" and see this page.

Send your support requests, with the above information, to: support@greenfoot.org
