Thank you for your suggestions.
The icarus website still isn't working and my pc won't install both versions at the same time.
What I forgot to say was that I'm running ADE on Linux mint. It's working well (apart from the bug) with winetricks, so I don't really think it has something to do with finding the reader.
Anyway, I am going to keep on trying it in the FAQ. The icarus support is no use. Their suggestions are, unfortunately, quite trivial.
