Ok, so I've been scouring google to no avail. I have finally downloaded an issue from Zinio that requires version 4 of their reader. I'd tried the AIR based monstrosity before and decided not to use it since it offered nothing I couldn't do with v3. That was on a G4 1.5ghz, but back when v4 first came along and AIR hadn't hit 2.x and went Intel only. This means, some version(s) of Zinio 4 existed that supported ppc, unfortunately ZiNio seems disinclined to have them available from their site, and all I can find otherwise are an hundred places to download 3.x. Does anyone still have a copy of the pre-AIR 2.x version of Zinio Reader 4 BETA, or better a link to where it might still be found? For those still trying to make sense of it based on info from Zinio: they haven't updated all the FAQs so some things just say a Mac running AIR 1.5.3. But if you try to install it AIR informs you that it requires a newer version of the platform and that said version isn't made for the hardware you're using. And, no, I can't just buy a new Mac. if that were an option I wouldn't be asking this (sorry, but I've seen such "helpful" replies to similar kinds of posts too often).
