Dear Paola, no problem, we’re almost there. Sorry, I forgot to adjust the PATH setting in terminal. I have $HOME/bin already in PATH in terminal. This is not standard, obviously - so let’s add it for the test :) This is the equivalent of adding $HOME/bin to LyX PATH settings. See the screenshot. Regards, Stephan
