Cannot visualization while running example B1

Hello there, I want to try running example B1 with visualization using OPENGL_WIN32 or QT (I use windows 10, VS2019, geant_10_06_p02 and QT 5.15.0), but still can’t visualize and this is the message what I get after running exampleB1.exe

error opengl.txt (8.4 KB)

hope can get best solution for this, thanks

do you have init_vis.mac and vis.mac in you directory where you execute the example?
