When trying to install Illustrator CC 2014 I get the following error:
Installation failed
Download error. Unable to reach Adobe servers.
Please check your internet connectivity, firewall settings, and try again. (502)
I have only just installed Photoshop CC 2014 and updated Photoshop CS6 via the Creative Cloud updater, as well as other updates so believe that it must be the Illustrator installation that is at fault.
I have restarted both the updater and my computer.
