I need to integrate rhino and grasshopper with Archicad for my design project for university. Sadly, every time I follow the set-up wizard for Grasshopper-Archicad 26 Live Connection add-on, the prompt "Grasshopper-Archicad Live Connection for Archicad 26 runs with up-to-date Archicad 26 versions only, no such Archicad 26 installation is found on your computer" pops up. This keeps popping up despite there being the Archicad 26 app located in the folder. I've followed all the steps, which includes downloading rhino and grasshopper before-hand, but to no avail. I've been using Archicad 26 with no problems, and I just really need this add-on to work so I can continue with my project!
Any help would be appreciated!!
