user manual


Support Suspended - Please Use Java 1.8

Launcher and Modpack do not support Java 1.9. Unfortunately I cannot afford to spend time on this until late October. In the mean time use Java 1.8.


This is the developer's page of the Launcher for Life in the Woods Renaissance. For the official release versions of the mod-pack and the launcher binary please visit the Life in the Woods Renaissance web-site.

For the helper mod, which was especially developed to improve usability of the Life in the Woods Renaissance mod-pack see here.

The Life in the Woods Renaissance Launcher is based on Open MCL.
