Adobe Arobat 11.0.23 - Can't change Content Editing app

I am running Adobe Acrobat XI version 11.0.23.  A while ago I stopped being able to open MS Paint to edit. I know that's a common problem. When selecting Microsoft Paint from the "Edit Using" dropdown menu, I receive a message saying I have to got to Preferences, then Content Editing and then choose Image Editor.  When I get to Content Editing, I only have one option ("Enable Artifical Bold/Italic Font Styles).  There is no Image Editor option/icon/drop down menu.  Any answers?  I've tried repairing the software, also moving the Preferences folder temporarily to a separate location.
