1 Versions earlier than 4.12 existed only on Mac. They could read file versions from 1.x- and could not write earlier file versions
2 4.16 was the first Windows version. This could not read Macintosh files, but there was a converter tool that ran on Mac and converted Mac archive (PLA) files to windows format and 4.16 Windows files to Mac format. (You can find this converter here)
3 From 4.16 till 6.5r4 on Windows platform the Sentinel protection key was used. The sentinel key could run earlier Archicad versions also protected by Sentinel. (e.g. a 6.5 key could run Archicad 4.16)
4 The Mac protection key (type Microguard for versions 5 and 5.1 and type Rainbow Sentinel for versions 6.0 and 6.5) was not backward-compatible, however the Archicad Install CD contained the previous Archicad version recompiled to run with the new protection key
5 From Archicad 7.0, WIBU protection key was used on both platforms. WIBU is platform-independent, the same key works on Windows and macOS. The Archicad 7.0 CD contained a special version of Archicad 6.0 (r5/v5), Archicad 6.5 (r4/v4), which runs with WIBU key.
6 Since Archicad 10 MacTel version is the first Archicad on this platform, it can not save earlier file formats. More on this topic: MacTel » FAQ
