Hi Stefan,

Sorry for the trouble. I would definitely recommend deleting and starting over with the binary installer. If you run into trouble with that, running the "GetLarch.sh" in a Terminal would probably be the most helpful, as it will create a log file that might have some clues about what went wrong. And, like Jeff said, if you don't get the Larch folder of Apps, typing

~/xraylarch/bin/larch -m

in a Terminal should remake those.

Dear all,

I upgraded a machine to 12.2 (MacPro), Larch was installed via binary installer. Afterwards Larch didn’t launch. I did a re-install with the binary installer and this didn’t work, because already installed. deleted it, but this also didn’t work

tried

pip install xraylarch

stopped
with
ERROR: Failed building wheel for fabio
Failed to build fabio

also no director with XAS viewer created.

best regards
