Compile this launcher for x86 ( also called i386 or i686 ), it can only load games with the same arch as the launcher.

The Launcher you built is for x86_64 and only looks for the lib/x86_64 folder and not any other lib folder.

Sounds like the error message could be improved

Thank you so much this worked

Compile this launcher for x86 ( also called i386 or i686 ), it can only load games with the same arch as the launcher.

how do I do that? do I have to modify CmakeLists.txt or the Makefile?
