I just bought Indesign CC for one month only, but there's no option to download the older version of Indesign.
see if this helps: How to Find and Install Previous Version of Adobe Apps in CC 2015 | Adobe Customer Care Team
unfortunately not. InDesign is not listed in there - maybe because I don't have the one-year-abo?
I do have the anual photography plan, so Photoshop and Lightroom are listed. Maybe it's really because of the month-to-month service?
