I keep getting an error with Rhino.Inside Revit after I start Rhino.Inside and then click on “Grasshopper” that says “Failed to load Revit Grasshopper Components”. We are working with Rhino 8 and after seeing the error I initially updated Rhino.Inside to the latest version, but am still getting the error.
When I press “OK” Grasshopper opens up but no Rhino.Inside components.
Please let me know what insights you may have on this.
Hi Maya,
What version of Revit are you working in? Is Revit installed in its normal location?
Typically this is a conflict with a revit Addin, in 2025.3 and above there is a Addin Manager that can help troubleshoot.
I had the similar issue. I uninstalled the Rhino and RIR and the reinstall. Now it works.
Its happening to me within both Revit 2024 and 2025. I did the update and also an uninstall and reinstall of RIR and still no luck.
At some point my colleague and I ended up removing my Rhino 8 settings file to let it rebuilt itself which actually helped, but then after a couple of hours the issue happened again.
Hi Maya,
Happening both 24 and 25 is a bit unusual. They run in different dotnet/runtime versions.
Isolating from both Rhino plug-ins and Revit add-ins is the way to troubleshoot.
Hi @Japhy! I’m experiencing exactly the same problem. I’m running Rhino Version 8 SR29, and Revit 2026. I’ve updated the RiR version to current one (Rhino.Inside Revit: 1.35.9540.6370 (2026-02-13T03:32:20) but the problem persists.
I’ve also uninstalled and reinstalled Rhino and RiR, with no change. I’ve also disabled the third-party plugins that do not ship with Rhino.
What else can I try?
@Japhy I’ve figured out that there seems to be a compatibility issue with a third party Grasshopper Add-on which is still in Alpha stage. After uninstalling it, everything works fine.
Which add-on was causing the issue for you? Been trying to narrow down which gh add-in is causing issues.
