Hi all, I have a customer who hits this error each time he click RUN in mobiflight.
May I know what could be the cuase? Thanks in advance.

Did they follow the instructions?

#

They have a Winwing CDU connected to their PC, and without Python installed it won't work with MobiFlight

I'm waiting for their results. That should solve the issue. Thanks Neil

THis has been working for me for weeks - and now that SU3 MSFS 2024 launched, I keep getting a "ERROR: PYTHON NOT READY" in my WingWing MCDU. What changed? I even reinstalled Python and added this command prompt command pip install gql websockets simconnect --upgrade --no-warn-script-location and it still doesn't work
