I am not able to launch the ganntt project app. I tried to launch is in admin mode, didn’t work.
I have tried to reinstall it. didn’t work.
I am on latest version ganttproject-3.3.3316 . windows version is 11 pro
When I launch the program, simply nothing happens, no error, nothing. dead silence.

Same here. Uninstalled Java Runtime, installed the correct one. Nothing happening. Doesn’t even try to start. No error message, nothing.

Please try running ganttproject.bat as shown in the attached video, and post the results.
In this video, an incompatible Java Runtime was used first, and GanttProject did not start. After changing JAVA_HOME environment variable to the runtime that comes with GanttProject (it sits in runtime subfolder) it started successfully.
