RIR - Not able to use Rhino 7

Hello,

I have revit 2025 and rhino 7 & 8
I did the RIR installation and I want to use Rhino 7 but is opening by default Rhino 8.
How can I solve this?

Thanks,
Jose

Revit 2025 had a major change in its code base to Microsoft NetCore 8 (from netframework 4.8), Rhino 7 runs in 4.8 and will not run in Revit 2025.

Rhino 8 had a major change as well to NetCore 7 and we are able run inside Revit 2025. Note that Legacy plugin/addins based in NetFramework may have issues running inside Revit 2025.
