At first thanks for your answers!
At the moment I really just configured the environment paths as shown:
from the folder located here:
And yes I'm using the recent stable version of KiCAD, because I've got the same problems with the nigthly build. So I decided to use the stable version, but..ehh.. same probs here.
So you think after configuring the environment paths, I also have to add those libraries via the eeschema? Same procedure for footprints and 3D packages?
Cheers,
