Help

GoodPlanCraftLauncher (GPCL for short) is a Minecraft launcher for Windows. These pages cover only how to use it once it is installed, and where to look when something breaks: no changelog, no project history.

These pages are written for 1.9.2. Your current version is shown under Settings → About; if your version is much different, a few options may be in a different place.

How to ask for help​

Email gamets@caellab.com. Include the following and the cause can usually be narrowed down:

  • launcher version, Minecraft version, and which mods are installed;
  • what you did before the crash (just installed a mod? changed Java? changed the memory setting?);
  • the error report exported from GPCL ("Export error report" in the crash dialog).

A screenshot of the crash window alone rarely carries enough information.
