LCE Qt Launcher

French Version

• Other Repo:
  • Backup repo
  • Data repo

Warning

This launcher is work in progress and its feature could be changes or remove at any time. PR are more than welcome to fix or add features. Just be compliant with the GPLv3 license and the Code of Respect

Note

The auto-update and installation of the game files is unstable and unviable, it is recommnend to have the game file already installation as the installation and update mechanism require external repo that can be shutdown without previous notice. I do my best and the nightly build are often up to date but the stable version sometime lack behind and require manual intervention.
