Here you can find hints and tips if you are having issues getting the AIR based SDK installer to work, as well as details of how to use the command-line to install the SDK using Ant without requiring AIR.
If you had installed a previous (pre-release) version of the installer app, you will probably get an AIR error because of the mis-matched certificates. If you see such an error, you may need to uninstall the installer before continuing.
Mac OS (10.9 or later)
You must allow unsigned apps (in Security & Privacy pane of the System preferences) in order to install. In recent versions of OS X, this became a blocking error instead of a warning by default. This preference setting allows to revert it to a warning, non-blocking message.
Linux
Adobe no longer provide updates for their installer for the AIR runtime used by the installer, so clicking the installer badge may give an error, or the package it sends you will fail to correctly install. Workarounds to install the AIR runtime are listed below, or (as of Apache Flex 4.12 nightly) you can use the Ant based method.

Ant installer
The Ant-based installer doesn't require AIR to be installed, or use the installer app, and is the preferred method of install on Linux.
Download the binary package (currently, this is the nightly build from https://builds.apache.org/job/flex-sdk_release/lastSuccessfulBuild/artifact/out/ but any release after 4.12 from http://flex.apache.org/download-binaries.html will work) and unpack it.

tar zxvf apache-flex-sdk-4.12.0-bin.tar.gz |
Now enter the unpacked directory and run the installer. You will need to tell it to download the last version of the AIR SDK that ran on Linux:. You can leave this argument off on other platforms.
