As far as I know there is not any way to perform uninstall/install time actions using the default AIR installers. I think you have to write your own installer/uninstaller wrapper if you want that kind of functionality.
can u help me how to start uninstaller wrapper functionality to delete those files from uninstallation.
thanks in advance...
Well.. to do that you have to pick an installer technology to wrap your AIR executable with - sort of making the AIR installer an embedded installer. Try something like http://nsis.sourceforge.net/Main_Page
