Error after update 9.0.25302.12305 with RhinoCAM 2025 plugin

How do I find out which DLL is being referenced in this case?

I doubt that RhinoCAM supports running in Rhino 9 yet…

RhinoCAM 2025 on version 9.0.25287.18305 works fine.

I’m wondering how to find out in this case which DLL it’s referencing?

The RhinoCAM people should be able to tell you that?

Well, you may have gotten lucky up until now, I don’t know. Normally they don’t release a version of RhinoCAM that is “officially supported” until near or at release time for a new Rhino version.
