It is great that Apache Flex has produced the new Flex 4.9.0, but I have been unable to figure out how to install this inside Flash Builder 4.7. It seems that Flex 4.9.0 is incomplete because of licensing, and that it needs to be built. Are there instructions anywhere?
Or, if it is possible to install Air 3.5 (or 3.4) inside the Flex 4.6 sdk, that would also be a good solution as well.
It seems that Flash Builder 4.7 now requires Air 3.4 in order to do debugging on the device over USB, but it comes with Air 3.1 inside Flex 4.6.
Here is the new Apache Flex installer for version 4.9
