Hello, I just downloaded the latest Apache Flex SDK Installer from http://flex.apache.org/installer.html which is verion 3.3.2 at the time of writing.
When I tried to install it on my macBook Pro using macOS Catalina 10.15.2, I get the following message: *This application requires an update to Adobe AIR that is not available for your system. Please view the system requirements <http://www.adobe.com/go/air_sysreqs/> for Adobe AIR and update your system accordingly.* The link opens http://www.adobe.com/go/air_sysreqs/ but that just redirects to https://www.adobe.com/404.html immediately. How can I install the Flex SDK on my computer? regards, Wim
