Hello! How can I install DYNAMO FOR REVIT 2019 184.108.40.20611 and core 220.127.116.1110 at the same time? Screenshot by Lightshot
The latest version for Revit 2019 is dynamo 2.0.4, I would therefore suggest you get that version instead of trying to get dynamo 2.0.3.

Dynamo builds are saved here if really do need a certain version: https://dynamobuilds.com/
The Dynamo for Revit integration is built off the Dynamo Core build. As such the team tracks both to allow troubleshooting, tracking, and resolution between issues which are related to the Dynamo core build vs the ones related to Dynamo for Revit (or Civil 3D, Alias, Advance Steel, FormIt, etc.).
