Hi @Leonardo_G_Pate,
You have Vray installed. In previous Vray versions there was some kind of incompatibility which didn’t allow VisualARQ to load, but this was already reported and fixed (https://discourse.mcneel.com/t/visualarq-rhino-inside-revit-problem/116671/3).
Please, update your Vray version and let me know if you still have the problem.
