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
