Hello, I have the following problem.  
Since the installation of Revit 2021, I can no longer open Dynamo 2.02 in Revit 2019. Does anyone have any idea what the problem is?  
Many thanks in advance

Upgrade to 2.0.4 and see if that fixes things. You don’t want to be on that older version anyway as it is missing a security fix.

Thank you, I will take an IT ticket today to get the 2.04 update installed.
