Problem: Deploying AIR in EXE

Hi -

I export my AIR app as an EXE. When I double click it, it installs just fine. However, when I try to deploy it with other exe files in a program I create using InstallJammer, I get the following error:

The application could not be installed because the installer file is damaged. Try obtaining a new installer file from the application author.

Here are the steps I'm taking using InstallJammer. Does anyone see something that would throw this error?

I'm using a tutorial here: http://bishoponvsto.wordpress.com/2010/03/10/deploying-air-application-with-air-runtimeredistributable-in-single-exe/.... 

This tutorial has you do the following things:

• Export your AIR app as an EXE file.
• Place this EXE file, the AdobeAIRInstaller.exe, and any 3rd party EXE files into a ZIP file.
• At this point you switch to your installer program (InstallShield or InstallJammer) and you create the actions that will do the following:
• Unzip the zip file you created
• Execute the AdobeAIRInstaller.exe, your AIR app EXE, and any other 3rd party EXE files.

When I go by this tutorial the AdobeAIRInstaller.exe installs just fine, my 3rd party EXE installs just fine, but I get the above error when installing my AIR app EXE:

Why is it that the EXE file would work fine on its own but throw an error saying the installer file is damaged when I try and run it from an Install program?

Thanks for any helpful tips!
