Running a test in flair

Hello Fluka users

I found some difficulties to run the basic tutorial on flair, just to see if everything works correctly,
I launched the simulation and in the bottom it’s mentioned “waiting to attach " ,and nothing happened and in the output it’s mentioned that " pwxs does not exist”, I have no idea about “pwxs” , is it the main reason and how can I fix it?

Thank you,

Best regards.
