Dyno won't start

Hi all,

I have Revit 2021 installed and when i try to open Dynamo from the top bar the following error ocour

than, if i try to open again the error changes, saying something like “GA Client is already initialized”

I tried to reinstall Revit but nothing changes

Are you using the latest Revit 2021.1.2?
21.1.20.44
20201109_1530(x64)
2021.1.2

Could you also let us know:

  • What’s your system configuration?
  • What’s your windows version?
  • Any Third party tools which you’re using?

Thank for your fast reply.

I checked my revit version and it was out to date, it was on version 21.0, so i updated it with 21.1.20 hotfix and dynamo work again, thank you
