When I use the Flex installer and install Flex/AIR, if I then attempt to build my application using IntelliJ, I get an error that crosspromotion.swc is missing. I have tried multiple combinations, but it is always missing and I have to go back to a very old version of my SDKs (that I can't recall where I installed from since I've had them forever) and copy over the crosspromotion.swc from frameworks/libs/air to the new SDK in order for it to work.
