3.0.3005 could NOT be launched in MacOS 10.15.7

GanttProject Desktop Support
#1

Current running ver: 3.0.3000.
Updated to 3.0.3005 and relaunch the porgram.
The system is pending with GanttProject logo window at the desktop.

I think that you skipped one of the updates (maybe 3003). You need to remove all installed updates, launch GanttProject again and let it update to 3005.

You can remove all updates by running this command in your Terminal:

rm -rf ~/.ganttproject.d/updates/*

It works now following yr instructions.

A post was split to a new topic: Michel DUPRES: update from 3002 to 3005
