User Reviews

  • The program is good but has lots of issues: 1. Calendar changes like vacations are not stored 2. Can't Zoom in the Gantt chart using the mouse wheel. You have to search for the zoom buttons in the toolbar 3. you can't use the wheel to scroll in the ganttchart or in the task list

  • Does what I need without paying for full MS Project.

  • Hi, for those who had "JRELoadError" message error, just download and install the last version of java and relaunch ProjectLibre; so, everything'll be ok.

  • Not usable - at least in Ubuntu it's too slow, unusable - resources still not possible to be shared among projects

  • Project Libre for Mac does not work at all: A message "JRELoadError" appears... Such a disappointment!!!
