Now i installed dynamo migration assistant for dynamo 2.17 from this directory “AppData\Roaming\Dynamo\Dynamo Revit\2.17\packages”.
But when i try to install dynamodoreruntime2.19.0 to here (“AppData\Roaming\Dynamo\Dynamo Core” ) dynma on revit completely disappeared.
Secondly i’ll give it a look this ( Updating python node in multiple scripts - #15 by jacob.small)
