G4Tree.lib G4GMocren.lib G4visHepRep.lib G4RayTracer.lib were some of the files that were mentioned in the cannot open input file error prompts. This is somewhat related information to the linked post I mention below. In the time between the date of this reply and the date of the post above, I have posted a total of three topics relating to running exampleB1(the above post is the second). The problems I have in this post have been resolved by uninstalling geant4 then reinstalling geant4, however new problems emerged that I don’t know how to fix which are mentioned in much more detail here (the third post)
