7.3 not allowing user to export for ad-hoc distribution using bit code

7.3 not allowing user to export for ad-hoc distribution using bit code.
Dont download 7.3 if you are doing ad-hoc distribution.
Wested 3 hours to figure it out and then downloaded 7.2.1 its working fine i.e. able to export for ad-hoc distribution
