Hi.

I followed the link which is given below to develop an air application .The procedure i followed is there in this link "http://help.adobe.com/en_US/AIR/1.5/devappsflex/WS5b3ccc516d4fbf351e63e3d118666ade46-7fd8.html"
I could able to generate swf file by compliling and i also tested the application.
But while packageing air installation file i am not able to do.
Here first i need to create a certificaticate i did that.
Then i entered the commands for creating air file,When i did this it asks for password but im unable to enter the password.If i strike enter key it displays procedure to follow but again samething is happening.
