The Installer can not be customized to do what you want.
Thanx a lot!
I have resolved this issue by using the application installation date..
Just tried to give a thought...and I got the solution..
Do you know, how to ask for login during installation?
I'm not sure I understand what type of login you are requesting, but it is possible to build a wrapper installer that silently launches your AIR installer then does whatever you need in a post install step (or preinstall for that matter.)
