RevitCat: Download and Installing Revit 2020
revitcat.blogspot.com › 2019 › 04Apr 15, 2019 · Well, it seems to have installed Dynamo 2.1 with Revit 2020, and it left earlier versions well alone. I had Dynamo 1.3.3 installed in Revit 2017, 2018 & 2019 - and all of those appeared to be intact. There is some more information on this here. Well, Autodesk have made a huge change to how Dynamo is installed and upgraded from Revit 2020 onwards.
