GanttProject freezes and OS shows error message "LoadLibrary error 1114" after clicking any button in the user interface


This issue should happen rarely because it requires a combination of certain conditions: OS, graphic adapters and drivers and energy saving settings. However, if it is reproducible then it is reproducible always.


There are two possible workarounds:

  1. GanttProject configuration change
  • If GanttProject was installed with Windows Installer and you run it using menu items then open file ganttproject.l4j.ini from the GanttProject installation directory (you may need to be Administrator) and remove the line -Dsun.java2d.d3d=false. Save the file.
  • If you're using ZIP distro and run ganttproject.bat then open ganttproject.bat in any text editor and remove string -Dsun.java2d.d3d=false from line 13
  1. Energy Saving options change (no kidding)
  • Open the Control Panel
  • Go into the Power Options
  • Edit Plan Settings
  • Change Advanced Settings
  • Switchable Dynamic Graphics
  • Global Settings
  • Change both settings to Maximise Performance
  • Apply changes and try again.
