I have an old CS5 Master install, and have recently upgrade InDesign to 2015.2. However, when I run a jsx file (by double-clicking in Finder), ExtendScript just hangs. When I kill it and go in and try to play the script, it asks me if I want to run InDesign CS4. Exact words 'Target Adobe InDesign CS4 is not running. Do you want to launch Adobe Indesign CS4'
How do I force ExtendScript to run the latest version of InDesign. I've even deleted the old CS5 version and still get the problem.
