Haven't seen this kind of error on askubuntu yet.
Did everything as it says here: How can I install Adobe AIR?
shows this image:
Meanwhile terminal shows a bunch of such messages:
(setup:2579): Gtk-WARNING **: Unable to locate theme engine in module_path: "murrine",
Nothing is installed. Those murrine - it showed another code before ( another than setup:2579) - I googled it, installed something, it showed another code - I googled it, installed something, etc. Doesn't seem to affect installation anyhow.
