I recently upgrade from Snow Leopard to Lion by purchasing the program via the Apple Store on-line, rather than purchase a disc. When I made the purchase I received a receipt via email, but there is no serial number for the program. Now that I have done the upgrade on my Mac Book, I would also like to upgrade my son's iMac but am not sure how to go about doing that If anyone knows how, please advise. Thanks!
