Rhino Plug-ins not Loading

Contact us if problems loading the plugin, package manager typically makes installation easy and reliable, installation issues are infrequent.

Sometimes however after updating a plugin, users experience a loading error. Usually this will report that plugin id is already in use. (Please post to this discussion if you are experiencing the problem so it might be resolved) https://discourse.mcneel.com/t/unable-to-load-plug-in-id-already-in-use/153552

This suggests that restarting Rhino might fix this issue, or you can uninstall the plugin from package manager, restart rhino and install anew. Alternatively the user needs to manually purge older versions of the plugin. You can locate the plugin install folder as per this screen capture (change plugin name if not ggRhinoIFC).

Rhino Option has a hyperlink to open folder containing plugin files.

You can then browse back one parent level folder. Close Rhino application, and select all folders with the exception of latest version. Delete the folders. Restart Rhino and the installation should be repaired.

Browse back one folder and select older version folders to delete.

Observe Grasshopper Loading Errors

As grasshopper starts it will generally provide errors if something has not loaded correctly. Check for loading error reports as grasshopper starts. If specific to Geometry Gym then please contact us as soon as possible.

Check Grasshopper Developer Settings

Run Rhino command GrasshopperDeveloperSettings and tick COFF loading. Previous versions commonly required COFF loading to be not checked, so try toggling if having problems.

Grasshopper Plug-in Not Loading

If you receive an error message like the one below when trying to open grasshopper it is likely that something is blocking the Rhino Plug-in counterpart from loading in Rhino.

Grasshopper Loading Error

Our Grasshopper add-ins are typically a satellite to our rhino plugin (this might change in the future). So you need to ensure the rhino plugin is loaded prior to Grasshopper starting. First, check it's not load protected in rhino options. Make sure it's not load protected and scheduled to load rhino plugin on rhino startup.
