1. Download the "SDK tar.bz2" version of Ren'Py from
You must be registered to see the links
and extract it.
2. You can rename this directory as you want, e.g. the game's name.
3. Move the "game" directory of the original Lust Campus directory inside the new directory and delete all other directories here, except "game", "lib" and "renpy".
4. Optionally you can rename the .sh, .py and .exe files if you want, but avoid using spaces and symbols (,!? etc) in the name. Go into the "lib" directory, then in the adequate Linux directory and rename the extensionless file "renpy" with the same name as the .sh, .py and .exe file (not "python", "pythonw", "zsync" and "zsyncmake").
Works for me!
