Hint for non-BIS users:
You can use the User Agent Switcher plugin (http://addons.mozilla.org/firefox/addon/59) for the Firefox browser and set up a new User Agent "BlackBerry8700/4.2.1" (replace 8700 with your BB model and 4.2.1 with your OS version if needed) to download practically ANY OTA installer in order to make your own ALX installer. Just switch to this fake BB user agent and open the OTA link, e.g. Gmail, so the web page will believe that your computer is a BlackBerry and happily deliver the .jad file.
