Creative Suite is no longer sold or supported.  Do you have a valid individual license for CS6?  And do you have an older OS to support it?

If yes to both questions, try this download link.  But be sure to follow the VERY IMPORTANT INSTRUCTIONS or it won't work.   Also, Adobe may remove these links at anytime without warning.
