I started following your instructions by removing all components of Rhino 6.30. First of all you are right that I have installed version 6.30. Hello back thanks again for all of your help. Rhinoceros and Grasshopper – developed by Robert McNeel & Associates – are considered market leaders in industrial design modeling and algorithmic design.Now, designers have various options to connect Archicad’s professional BIM work. Link to the mentioned PlugIn: Graphisoft Rhino – Grasshopper – Archicad Toolset I hope very much that someone has an idea on how to make ArchiCAD Grasshopper Live Connection useable for Rhino 7 WIP Beta. Unfortunately the installer program does not recognize my Rhino 7 WIP Beta version, even if Rhino 6 is not installed. The occurring problem is, that I am very often using ArchiCAD 24 and the ArchiCAD Grasshopper LiveConnection together. Moreover Rhino 6 is still producing unreasonable activity of the fans, even on very reduced files. When it comes to navigation on canvas, the screen is very slow, scrolling and clicking commands are very slow as well. Unfortunately I noticed that Grasshopper has heavy performance issues with smooth frame rates. Most of my plug-ins at my component folder are working correctly. I started using Rhino 6 and Grasshopper on Mac Catalina 10.15.6.
