CS4 won't publish to AIR - error help please!

Question

hi guys,
our machines (XP, Flash CS4 pro, Air 1.5) are failing to publish AIR files.
even creating a basic hello world *.fla exporting to AIR on default settings will fail with the following error:
"Error creating AIR file."
"Application descriptor file cannot be parsed"
I have also tried creating a basic custom descriptor file but this has the same effect:
<?xml version="1.0" encoding="UTF-8" standalone="no" ?>
<application xmlns="http://ns.adobe.com/air/application/1.5">
    <id>com.adobe.example.main</id>
     <version>1.0</version>
     <filename>main</filename>
     <description/>
     <name>main</name>
     <copyright>2010</copyright>
    <initialWindow>
         <content>main.swf</content>
         <systemChrome>standard</systemChrome>
         <transparent>false</transparent>
         <visible>true</visible>
         <width>650</width>
         <height>400</height>
         <x>0</x>
         <y>0</y>
         <maximizable>false</maximizable>
         <minimizable>false</minimizable>
         <resizable>false</resizable>
     </initialWindow>
     <customUpdateUI>false</customUpdateUI>
     <allowBrowserInvocation>false</allowBrowserInvocation>
</application>
can anyone shed any light on this issue as it's killing our work flow.
regards, Rich

Answer 1

I'm running into this same problem; glad to see others have too (and fixed it). Now, I'm completely self-taught with Flash, so I'm not too keen on many terms. Could you better describe to me what (and where and how) you messed with that caused (and fixed) the issue? This is my first project in which I changed (or rather set) the source path for my .as files. Is that what you're talking about?
