I created an AIR2 file and send to a friend. He was asked to update Adobe AIR and now Zinc, which he was also using is not working in his other movies any more. Also I posted in a different post that AIR files, which I sent him did not work at all even he had the correct AIR version (1.5) for that installed. They worked on my computer (Mac). Why does Adobe officially release AIR versions in CS5, which cannot function.
