安装64位air
Download the Adobe AIR .deb file
http://get.adobe.com/air/
In a terminal window go to the directory containing the adobeair.deb file
Create a tmp dir:

mkdir tmp

Extract the deb file to the tmp dir:

dpkg-deb -x adobeair.deb tmp

Extract the control files:

dpkg-deb --control adobeair.deb tmp/DEBIAN

Change the Architecture parameter from “i386″ to “all”:

sed -i "s/i386/all/" tmp/DEBIAN/control

Repackage the deb file:

dpkg -b tmp adobeair_64.deb

Now you can install Adobe AIR on a 64-bit system! From the command line just do:

sudo dpkg -i adobeair_64.deb
