Hello, my revit2019.2 can not open grasshopper, previous use revit2019.1 can not open grasshopper. But revit2022 will open grasshopper no problem.

revit:2019.2 rhino:rhino7

What version of Rhino & Rhino.Inside.Revit?

You can get that in the About tab of Rhino.Inside.Revit.




Ljunliang, You are fairly up to date. Do you have any old Revit Add-ins only installed on 2019.2? Lets remove any that you don’t use anymore, then check any remaining for a conflict with this tool.

There are only a few additional modules, and I don’t know if any conflict with Rhino.Inside.Revit.
