Grasshopper-Archicad 28 Live Connection User Guide download link unavailable

[enz_mc]

Hello,

The link to the User Guide for 28 Live Connection for Windows seems to be unavailable, here:

https://graphisoft.com/downloads/addons/interoperability/rhino/

When opening the User Guide link, it says "The resource you are looking for has been removed, had its name changed, or is temporarily unavailable."

Would anyone know where else I could get a copy of it?

Thank you!

Operating system used: Windows
