I’m experimenting with the RiR add-in for Revit (2019) and keep running into this error, followed by an exception crash as follows
Error HRESULT E_FAIL has been returned from a call to a COM component.
at Rhino.Runtime.InProcess.RhinoCore.Startup(Int32 argc, String argv, StartupInfo& info, IntPtr hostWnd)
at Rhino.Runtime.InProcess.RhinoCore…ctor(String args, WindowStyle windowStyle, IntPtr hostWnd)
at RhinoInside.Revit.Revit.OnStartup(UIControlledApplication applicationUI) in
I can start the WIP Rhino with no issues and the Rhino 6 (both showing the version 6 serial number) so I assume they are both licensed
The Rhino-behind Revit starts but of course no buttons in Revit are created
Any help would be appreciated
