Thanks for all your work on this Piotr. Unfortunately, installed 3.3.1 is failing for me at the point of "Flash SDK" download (for AIR29). I'm running this under Windows 10 and I've tried it on two different systems. Coming back to it a day later hasn't helped either (I know sometimes hashes are out of sync).
This is the error it's outputting: /Installer version 3.3.1 (windows) Using Locale: en_AU Fetched the SDK download mirror URL from the CGI.
