This updated fine on an older iMac, NOT yet updated to El Capitan. I've had issues with the latest CC programs in El Capitan on this new machine, and have had to use the 2014 versions. Was hoping this update would fix those.
I will try that (uninstall and reinstall have been done several times previously, but I'll give it another go). And just so you know, there are other comments from people who are also stymied with issues in these programs, conflicts that appear with El Capitan. I'm really NOT the only one. Every other person with problems has said that we just have to wait it out until the developers hit upon an update that will work for us.
