I have had this problem for over a year now; that's how long I have had Adobe Cloud and Illustrator. No matter the version (i.e. 64-bit or 32-bit, 2014 version or other), it has NEVER worked. I've tried all the suggestions above and below and even spent time online with a tech last year who said they'd get back with me and never did. We completely uninstalled it and loaded it onto another drive; no dice.
ALL other Adobe products work fine. All other programs on my system work fine, regardless if they are Adobe or not.
THIS NEEDS FIXED!
