"Assembly resolver failed to load assembly"

[Japhy]

Note that there is a See Details option to get more info in the dialog.

Lets first start by updating to the Latest Rhino and Rhino.Inside.Revit

https://www.rhino3d.com/inside/revit/1.0/

Then lets troubleshoot Revit Plugins and if need be Rhino/GH plugins.

3. Additional Troubleshooting Methods

You can Cntl+Shift on the Rhino start button on the Rhino Ribbon in Revit to get this dialog.

If you are experiencing odd behaviors it could be a Grasshopper plugin.

You can troubleshoot by opening grasshopper via the Rhino command line with the GrasshopperLoadOneByOne command.

Its also easy to move grasshopper plugins out of their folder temporarily so they won’t load.
