Hi, The Adobe AIR SDK 24 is available in beta form at [1] and is incompatible with our installers (both for regular Flex as well as FlexJS). So, our users currently will not be able to use the Installer or Ant to set up with Adobe AIR 24 or later. I have created JIRA issues FLEX-35166 and FLEX-35167 to track.
Apparently, the Adobe AIR SDK contains executables like ADL and ADT and security software is starting to flag and prevent delivery of executables via compressed archives, so Adobe decided to switch from ZIP and TBZ2 files to EXE and DMG files. I can't imagine Adobe changes its mind on this, so I think our installers simply have to respond. This also means that, without some serious hacking in our Installer, that folks will never be able to install current or older Flex and FlexJS SDKs with Adobe AIR 24 or later. We need to decide how urgent this issue is, but I'm assuming for now that folks want to see the next Flex SDK release work with Adobe AIR 24 and later. -Alex
