The meshing works on my machine. Maybe you are missing some Gmsh files?

I know this should work. I have Gmsh installed. How can I check the configuration or add Gmsh to ProPeMax?

Problem solved, topic to close. I hope I could help others :slight_smile:

The problem was that in Windows I had unnecessary files from the old version of GMSH:
