I/O warning : failed to load external entity “/etc/opt/Adobe/certificates/AIR/crypt//config.xml”
Unable to parse Document: /etc/opt/Adobe/certificates/AIR/crypt//config.xml.

Just edit the application.xml in META-INF/Air and comment out the publisherID tag. Bit ugly but it works

Just to give back, here’s a nice little scriptlet I wrote in Perl to launch an AIR app without all the BS. Just copy it into a file called airlaunch.pl in your /opt/AIR-apps directory, hardlink /usr/bin/airlaunch to /opt/AIR-apps/airlaunch and you won’t even hardly notice a challenge.

##BEGIN SCRIPT##
#!/usr/bin/perl -w

# AIR Launch!
#
# Used to start an Adobe AIR application in nodebug mode.
# DO NOT USE WITH A TEXT ONLY CONSOLE! You could break something.

$adl_binspec = “/opt/AIR-SDK/bin/adl”;
$sys_airspace = “/opt/AIR-apps”;
$usr_airspace = “$ENV{‘HOME’}/AIR-apps”;

die “AIR not installed! Expected adl at $adl_binspec.\n” unless -e $adl_binspec;

die “Do NOT use this with .air files! Extract them to $sys_airspace or $usr_airspace first!\n” if $ARGV[0] =~ /\Q.air\E/;

$app_name = $ARGV[0];

if ( -e $app_name )
{
$app_path = $app_name;
##Perhaps the user gave us a fully qualified path! ##

elsif ( -e “$sys_airspace/$app_name” )
{

#Check what apps the system has installed!
}
elsif ( -e “$usr_airspace/$app_name” )
{
$app_path = “$sys_airspace/$app_name”;
##Maybe the user has the app installed in their AIR directory?##
}
else
{
die “Could not locate application \’$app_name\’.\n”;
##Nevermind, the user is a complete cock.##
}

##Now check to make sure the xml file is there. This file spec could change at Adobe’s whim!##
if ( -e “$app_path/META-INF/AIR/application.xml” )
{
$command = “$adl_binspec -nodebug $app_path/META-INF/AIR/application.xml $app_path”;
}

##END SCRIPT##

I had an extra issue because I’m an Awesome user, but there’s documentation on the Adobe website which got me past that final speedbump and lets me run AIR apps as well ( http://kb2.adobe.com/cps/492/cpsid_49267.html –> check the bottom of the page)
