We’re looking into a proper fix now - it appears, as Gavin mentioned above, to be an installer build issue. We’re working on properly identifying how to resolve this issue 
WARNING: Dangerous approach to use at your own risk below...
If you want to be adventurous and live on the edge, you can replace the DynamoNodes.dll attached here inside your DynamoRevit installer.
This comes with a few caveats:
- We take no responsibility for any problems that occur should you choose to take this action.
- If something goes wrong and breaks, it may cause you to have to reinstall Revit. Theoretically it shouldn’t.
- This didn’t blow up my install and worked perfectly fine, but there have been issues in the past.
- Take a copy of your existing RevitNodes.dll just in case and place it somewhere safe, so that you can put it back if needed.
- To attach to the Dynamo Forum the .dll file been renamed into a .txt file, so you’ll need to rename it back to simply RevitNodes.dll for Dynamo to recognize it.
- The attached RevitNodes.dll contains the fix, and will unblock the problems in this thread.
- After downloading the RevitNodes.dll make sure to right-click on the file, go to Properties and unblock it so that Windows will trust the file and allow it to be read.
- Your RevitNodes.dll will live under
