I do appreciate all the responses helpfully telling me to disable my adblockers, but I have attempted this download across three browsers, turned off my antivirus, and logged into the site via a proxy to ensure it was not my internet connection.

I do not believe ad blockers are the problem.  (Windows 10, most up to date versions of Chrome, Firefox and IE 11.)

Like everyone else, I am getting the following error:

This site can’t be reached

airdownload.adobe.com’s server DNS address could not be found.
