Hi Eugen!
We have noticed a similar problem to run VisualARQ inside Revit when VRay is also installed in Rhino. I don’t know if it’s your case, and I don’t mean it’s Vray’s fault, but we still need to figure out how to fix it.
There is a manual workaround, if this is your case:
- Close Revit and Rhino.
- Find a file called “VisualARQ.Script.dll” in this directory: C:\Program Files\Rhino 7\System
- Move it to this folder: C:\Program Files\AsuniCAD\VisualARQ 2\RHINO7\System
- Try to run Rhino and VisualARQ Inside Revit again.
Let me know if this still doesn’t work for you and we will try to find a different solution.
