I downloaded Pro DC for Mac and the installation went well until at the very end I had the message "An instance of Adobe Acrobat Pro is running. Please close the application for all users and retry". I do have Acrobat Reader DC installed but not running. I closed the program on both other computers and also Adobe Acrobat Pro which is one of my earlier versions that I had successfully downloaded in error. My next message was "Found a higher version Adobe Acrobat DC in the installation location. Installation will terminate". I wish I or "Spotlight" could find it, only Adobe Acrobat Reader DC" which is not running.
