Hi Erik Thanks so much for your very comprehensive and generous reply.
Using an Ad Hoc provisioning profile rather than distribution solved the problem of the app not installing. I don't recall having to do this last year ... maybe Apple have changed this and separated out ad hoc and distribution. Anyway, that sorted it. My Flex 4.15 build runs OK but the Flex 4.16 build crashes on launch. My best guess and next step is to upgrade to the latest versions of Milkman Games' GoViral and StoreKit which I use. I think the most recent one of these if for Air 25 so that's most likely what is causing the problem. Thanks too for the pointers on IDE and console. Really helpful Erik.
