Adobe Air and Content Viewer on Kindle Fire

How do I install/use Adobe Air on my Kindle Fire?  I have it installed on my PC and have tried to install it on my fire using a USB.  It seems as if it works but when I look on the Kindle Fire it's not there.

Also - how do you use Content Viewer on the Kindle Fire.  I have the app and it launches fine but I don't know how to get documents into it to view.

Any help on these questions would be greatly appreciated.

Thanks very much.
