ARCHICAD-20-USA install doesn't work on High Sierra

[Ugljesa Janjic]

Hello hello,
I am switching computers and trying to use the old installation file for ArchiCAD 20. It is not working.
Is there a place where I can download a new version of ARCHICAD-20-USA whatever the latest build is? I looked under the Downloads but couldn't find the old versions.
Any help will do. Thanks!

Got it to work. I used the old installation file that I saved from way back when I installed the version 20. What I had to do is to install the new update before even starting the program. Not sure exactly how and why it worked but it did. The old build was 3016, and that is way old.
Just wanted to share in case anyone else runs into this.
