The Apache Flex SDK Installer is an application that simplifies the download and installation of the Apache Flex SDK and its (required) components. It is aimed at anyone who wants to use the latest release of the Apache Flex SDK, but who might not necessarily be familiar with the tools and procedures required to compile the Apache Flex SDK from source code. The application will grab the official, current release of the SDK from apache.org, install it onto your computer and prepare it for use with Adobe Flash Builder. Use the badge below to download the Apache Flex SDK Installer. If you had installed a previous (pre-release) version of this 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 it before continuing.
Alternatively, you can download the source and/or binaries for the Apache Flex SDK Installer directly:

The Apache Flex team is pleased to offer this 3.3 release of the Apache Flex® SDK Installer, available as of 16 November 2017.
Binaries are provided as a convenience for those who do not wish to compile the installer themselves. The 3.3 binaries were published on 16 November 2017. There is no 3.3 convenience binary for Linux as all recent Flex and FlexJS SDK's support installation via Apache Ant and it was determined that Linux users preferred the Ant method over having to install Adobe AIR to install the SDK.
