After many months when I gave up with it completely, because it never worked, but hardly the same error message twice, I recently had a fresh try with this, and found they'd launched a whole new interface, which was called iPlayer Downloads, instead of iPlayer Desktop, and (for the moment) seems to work better, without spewing forth error messages about Adobe Air all the time, or failing to install at all, or failing to download at all, or insisting it wasn't installed, when it was...
But, one fly still in the ointment. "Series download" seems to have disappeared, leaving only: "Favourites", which I assumed should have assumed the same function - i.e. once you've designated something a "favourite", it should collect every episode as and when it becomes available, without having to manually initiate each download.
I can't get this to work at all. Marking something a favourite doesn't seem to trigger any downloads, either immediately, or at all, even when there are undownloaded episodes clearly available. All it seems to do is make them more easily accessible from the navigation pane, but doesn't affect download behaviour at all. So it appears I must remember to manually download every individual episode of a series, and if I forget, tough!
Can this be right? Is there really no series download any more, or is "Favourites" meant to do it, but just not working properly?
This is with Chrome on Windows 7, btw.
