Hi all! Having troubles launching Grasshopper through Revit in 2020 and 2021. I get the following error:

It’s working fine in Revit 2022. RIR version 1.6.8159.20547. Is anyone having a similar issue?

There might be a plugin conflict with a plugin not installed in Revit 2022

Thanks, that was it. The plugin causing this is called Unitize. It didn’t cause any problems before, usually it was either Vray or Enscape.

Thanks for reporting and getting back to us with the name of the conflict.
