As soon as I open rhino inside revit I see the error that is typed above. I was able to use grasshopper but as soon as I placed the brep param component in grasshopper it started showing the error in the screenshot. I’m currently clueless how can I solve this since I tried uninstalling and re installing the softwares too. I’m using Rhino 8 and revit 23.

Hi Kshitijnashine96,

About info for your versions is always helpful.

> [@Help Us Help You - Rhino.Inside.Revit Edition](https://discourse.mcneel.com/t/help-us-help-you-rhino-inside-revit-edition/170291/5):

> 1. Basic About Information You can find a complete About info here in the Revit Rhino Ribbon

The second step to troubleshooting is isolation the environment from potential 3rd party conflicts.

> Hi Junghwo, Lets troubleshoot for plugin/addin conflicts. open an new instance of Revit by Shift+Cntl clicking here (green dot) and selecting the first option (blue dot) Then open Rhino and start grasshopper via the GrasshopperLoadOneByOne command, saying no to 3rd party plugins. Ideally we can narrow it down quickly with these methods.
