Existing AIR Applications Won't Run in Flex 3? Quick Fix.

Posted on Feb 26, 2008

This is a quick post on a simple problem in case anyone runs into this issue and can't determine the reason. I had existing AIR applications set up in my beta install of Flex 3. As recommended by the installer, I removed the beta before installing the final version of Flex 3 released yesterday. ObviouslyI open Flex 3 for the first time, my pre-existing projects are missing. To import them with the prior settings, you simply go to File > Import > Flex Project, choose the "Project Folder" option and browse to the project folder location.

The catch is that since I also updated my install of AIR to the final version I was finding that hitting "Run" had no result...nothing happened. Well, what I needed to do was open the AIR application's XML descriptor file and change the line that read:

<application xmlns="http://ns.adobe.com/air/application/1.0.M6">

...(for the last public AIR beta) to:

<application xmlns="http://ns.adobe.com/air/application/1.0">

...for the current 1.0 final release.

Sorry for confusing.I'm just a newbie.I'm trying to do with an AIR application simple hello world., fortunately i just able to resolve problem. I fix it by ending/kill existing process (adl.exe) in windows task manager then rerun the AIR app again.

I've been having the same error on Flex Builder 3.0.2. The only difference is Air 1.5 is installed, and my app is set to 1.5 and it still happens. Any ideas?

The same problem with AIR 1.5

Change <application xmlns="http://ns.adobe.com/air/application/1.0">;

to
<application xmlns="http://ns.adobe.com/air/application/1.5">;

to get the air application started from Flex Builder with the Air 1.5.
