User Reviews

  • Importing a MPP-File (at least a file written by MS Project 2016) fails without any warning, as the lines are mixed up and thus headlines and tasks do not match. This is totally unusable. ProjectViewer365 and MS Project (even old versions) can open that file without failures.

  • I am a regular user of Primavera P3 and Microsoft Project and I tried to use the ProjectLibre several times as the free alternative. Unfortunately I realized that the ProjectLibre calculates the schedules WRONG and gives absolutely wrong dates. This applies to even smaller project schedules with a simple structure with less then 100 activates. Therefore it is not usable for me. It is a bad copy of Ms Project 2000.

  • 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.
