- How can I install Adobe AIR? 6 answers
Any solution is not do anything on my machine. I downloaded air Installed 32 bit packages but always said "permission denied"
In terminal (What is a terminal and how do I open and use it?) copy and paste each command then hit enter one command at a time.
With adobe air u need to use Adobe Air version 2.6 (only one I were able to run on 64 bit 12.04) since adobe stuck support for Linux. Never version most likely wont work at all.
Second issue with adobe air is that it mostly search for needed libraries on wrong place, however this post here!, helped me to instal Adobe Air.
