If you receive an error such as the one above, then most likely the extension has been included but not packaged with your application. You'll need to double check the project settings:

Actionscript Build Packaging / [Platform] / Native Extensions / make sure the extension is checked

And ensure that you have correctly added the extension id to your application descriptor:

<?xml version="1.0" encoding="utf-8" ?>
<application xmlns="http://ns.adobe.com/air/application/26.0">

    <!-- OTHER DESCRIPTOR INFORMATION -->

    <extensions>
        <extensionID>com.distriqt.Vibration</extensionID>
    </extensions>

</application>
