I'm trying to excute the DVD with Adobe Acrobat XI Professional Installer & Enfocus PitStop Edit 12 Installer for MAC. I load the DVD and when I open it, the PDF Support Application icon displays with a line across it and once I double click on it I get the message: You can't use this version of the application "PDF Support Application" with this version of macOS.
Your thoughts?
macOS Sierra v. 10.12 on MacBook Pro (15-inch, Early 2011)
