Opening an old C# script issues

Hi, I am trying to open up a grasshopper C# script I found on a forum. The file is a bit dated, and I cannot seem to find the Grasshopper plug-in folder as shown in the image below. Has the folder structure changed in the latest version of Rhino?

My Folder:

Try with: C:\Program Files\Rhino 7\Plug-ins\Grasshopper\Components\GalapagosComponents.gha

Didn’t see GalapagosComponents.gha file in this folder. Is this something that needs to be installed? I thought this is something that comes in by default when installing Rhino.
