Need ArchiCAD 18 direct download link, so I can "save down"

[Gus]

I need ArchiCAD 18 direct download link, so I can "save down" from 20 to 19 to 18 to 17 for another Architect to use since he only has 17.

I cannot for the life of me find a download link to 18 without going through "myArchiCAD" page. It's a little bit of a side problem that I have never been able to log on to that page due to a glitch in Graphisoft's log-in system.

I have ArchiCAD 20 and 19 already on my system and I'm an ArchiCAD Plus member whatever that means beyond the obvious subscription.

Does anyone know where I can download 18 without going through MyArchicad site?

Is this http://www.graphisoft.com/downloads/archicad/install/AC18/USA/ what you are looking for?

Yes, that worked!
Thank you so much!
Now I need to find the same for 17 but when I changed the link you sent me from an 18 to a 17 it took me to the 17 page, but the link button said that the 17 version was unavailable. So now I need to search for that. Any thoughts?
