Read indicates which is the oldest file format that the program can read Write indicates which is the oldest file format the program can write Protection indicates the oldest Archicad version that runs with the protection key that is supplied with the program's given version
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
