With dynamo 1.x and 2.x both in use, we would rather have the choice which version we want to use by default rather than having to choose which version we want to use each new revit session.
At the dynamo forum I suggested a new revit.ini block:
[Dynamo]
DynamoDefaultVersion=2
DynamoPlayerDefaultVersion=2
But I'm up for any improvement on this matter!
This would trigger the default version to 2.x rather than a 1.x version.
