@erfajo - The packages that contain zero-touch nodes that use the Revit API will fail to load at compile time if the Revit API is not present. That means that these packages will not show up in the library.
Depending on which client and version you use, the default folder for where the packages are installed to and called from vary:
- For D4R, the default package folder is Users\username\AppData\Roaming\Dynamo\Dynamo Revit\D4R-version\packages
- For Dynamo Studio, the default package folder is Users\username\AppData\Roaming\Dynamo\Dynamo Core\Dynamo Core version\packages
Please note that you can always add more paths for each client (D4R or Studio) to search for packages in, you can do this using the dialog found in Settings > Manage Node and Package Paths…
Lastly, just to clarify about version numbers, etc. If you have both Dynamo for Revit and Dynamo Studio installed on your machines, the following 3 items will be installed on your machine:
- Autodesk Dynamo Studio 2017
- Dynamo Core
- Dynamo Revit
Each of these 3 programs will have their own version number. Sometimes they might even look like the same number. When both D4R and Studio are installed on your machine, they will share a common Dynamo Core.
For specific questions about your particular setup, it would require providing the team about those 3 version numbers, what version of Revit you have installed, what paths you are pointing to in the Manage Node and Package Paths dialog. We would need those in order to determine if a bug exists or if something is missing with the setup.
Hope this helps.
