Hi there,
once a day Revit asks me to select the Dynamo Version (1.3.3 and 2.0 installed).
Later, this question does not appear anymore.
How can I change the Dynamo version, used by Revit, manually?
My target is to compare the Dynamo version 2.0 (not used yet) to the version 1.3.3 (used until now).
Must i delete some temporary file or deactivate any setting in Revit?
One way is to close revit and reopen it. Then you are asked again when you relaunch revit 
It’s actually that easy, I thought I already tried this …
Thank you very much
Hello! I have the same issue. I am now running version 2.0 and cannot access the package Sastrugi Package Version 0.1.4 that I just installed. The scripts are not appearing when I set the folder to the directory of where the scripts are. I though it was because of using 2.0 instead of 1.3.3, so I rebooted Revit, but does not give me the option to select the version of Dynamo as it once did after the update.
