I want to set up a download page to download my Air app, is there a way to detect if Air is installed so you only have to download/install the app or if the person needs to install Air first?
Have you tried using/creating a Badge?
Badger (AIR App to create badges): http://www.adobe.com/devnet/air/arti..._air_apps.html
If you use Aptana to create your AIR apps, it has a built-in badge creator, which can be accessed by opening your Application.xml file and clicking the "badge" tab normally located on the bottom of the editor (depends on your "perspective")
Thanks a lot! I have just started using Air so I didn't even know about this.
no problem! Badger can be a bit... wonky... when creating your badges, so you will more then likely have to create and test quite a few until you get one working exactly like you want it to.
Also, do no forget to add <allowbrowserinvocation>true</allowbrowserinvocation> to your application.xml file!! (i do it all the time :P)
