Steps to reproduce

1. download Dynamo Sandbox 3.1.0 and run
2. install Civil 3D 2025
3. not able to get Dynamo (3.0) inside Civil 3D 2025 to run

the workaround I did, change the Core folder under C3D\Dynamo\ to be the one from 3.1, and then I can get Dynamo running inside Civil 3D 2025. But I would like to run the original from Civil 3D.

Please help

PS: I already tried this but it did not help
