The problem looks as though it has something to do with mx.modules.ModuleLoader - does anyone know if any change in AIR3.4 has affected this component?
Fortunately no-one else has downloaded AIR3.4, so everyone else is still working.
Wrong, maybe everybody else is not just downloading and instaling AS IS, but rather downloading and saving these AIR Updates so if things do not go like planed they will be able to rectefy the problem! On the other hand if you would use Flex 4.0 onwards and still use the mx as I do then you would have maybe more likely not the problem you encounter right now with Flex 3.5, and as I do use Flex 4,0 with mx only and all my web or AIR Apps (96% with modules) are all working very well with AIR 3.4! regrds aktell2007
Do you mean that from AIR 3.4, sdk 3.5 is no longer supported?
