I've installed AIR and the iPlayer downloader, and so far neither have really worked.
Granted this is probably because I'm using 64-bit Linux, and they don't seem to support it yet (not that I was told this at any stage of the installation process, or the website where I downloaded the installer.
To get the thing installed on 64-bit I followed these instructions, and then proceeded to the BBC website to download something. Nothing seemed to work, no download links appeared. I then followed the links to an episode of Never Mind The Buzzcocks that other people reported was working. This time a download link appeared, but clicking it took me to install the program again.
To figure out why it wasn't working, I ran the downloader from the command line. It was printing the following: "Unkown desktop manager((null)), only Gnome and KDE are supported". Aha... I'm using XFCE, yet it must use the inter-process communication of either one of those desktops...
Booted into Gnome, and tried again. This time it tells me that it wants libgnome-keyring.so - I realise that no preferences are savable - it must be saving prefs with the keyring. I think that's a bit odd - what's wrong with ~/.Adobe/AIR?
After installing 32-bit libraries for gnome-keyring, the thing still doesn't work, and still won't download anything.
The problem with this application, or rather with Adobe AIR, is the series of arbitrary choices the designers seem to have made. Linux is not a platform where you can assume many things - and it would have probably made more sense to pick some generic ways of getting things done (there's a reason that text-files have always been used for config!) rather than relying upon fairly specific libraries for basic tasks and then not even falling back to a sane alternative. Perhaps a 64-bit version will fix all of this, I certainly hope so!
