Error with adl.exe while building a ActionScript only AIR App

Currently I'm trying to create a ActionScript only AIR app, as a demo for the iPhone. To start with I created a Flex project in the usual way:

• File new Flex project, select the Desktop application

• Click next to the set output folder, change that if you want

• In the Source Path tab change the file extension for the Main application file from MXML to AS, click finish

This will create a new project containing a ActionScript file that extends Sprite, now you can create a ActionScript only AIR project.

While I was doing this the first time I ran the project in Debug mode, and I received this error message:

Process terminated without establishing connection to debugger.

Command:

C:\FlexLibraries\FlexSDKs\flex_sdk_3.5.0.12683\bin\adl.exe C:\TFSWorkspace\TestProjects\Flash\iPhoneDevelopment\iPhoneAIRApp_demo1\bin-debug\iPhoneAIRApp_demo1-app.xml C:\TFSWorkspace\TestProjects\Flash\iPhoneDevelopment\iPhoneAIRApp_demo1\bin-debug 

Output from command:

invocation forwarded to primary instance

What this is trying to tell you is that you have two instances of ADL.exe running, to solve this problem I went into Task Manager and ended the two ADL process which were running.
