Ok, solved. It looks like I downloaded the x64 version of the plug-in but was attempting to load it into a 32bit Rhino. Of course. I doubt anyone uses that version of Rhino, neither do I. It was a mistake.
could you send me a screenshot of your rhino loading splash screen? The important part is the version number; we might have upgraded to a newer sdk release and, consequently, caused this problem - but not entirely sure. We’re using 6.1.18.
is by any chance the .rhp blocked, or any of the more obvious dlls in there? would ideally like to see the stack trace of this - does rhino provide more info besides the rather cryptic warning you showed us earlier?
Okay, that explains it then - i think. somehow, during the install, you might’ve unselected the misleadingly named SpeckleCoreObject Model:
This means that it didn’t get installed in its traditional place, which, on my machine is at C:\Users\dimitrie.stefanescu\AppData\Local\SpeckleKits. Can you try running the latest installer again? Thereafter, you should see a SpeckleKits folder in your local app data folder, which should contain the required dlls.
Let me know if this helps you out. Otherwise, if there’s no specklekits folder there must a problem with the installer and your specific setup; in which case I’ll have to look deeper.
