How to package AIR 2 native installer?

I have made an AIR 2.0 app that uses NativeProcess so it needs to be packaged as a native installer (.exe) rather than a .air file.

I first tried using Package Assistant but I kept getting an error telling me it cannot load keystore file. so I tried using the command line

I use:

pathToAirSDK/bin>adt -args

but I get an error telling me that

'java' is not a recognized as an internal or external command...

Has anyone packaged a native installer for an AIR 2.0 app? How did you do it?

edit

forgot to mention I am doing this in windows using the windows command lin开发者_运维技巧e.

After installing the Java JDK it worked. I do not know why I needed to have the JDK installed since I was not making a java app.
