Hei Erich
Thank you for this assistance in this improbable day.
Everything has worked fine with the previous release of MCUxpresso. This update is not doing well
The update I can supply now is this

If I try to launch a debug from a previously working project.
The directories mentioned in this message are not consistent.

That's the directory tree in the path..
The installation did not go properly. Maybe be it is simple to accomodate..
I am here
Thank You
Pietrro
