When I try to open an embedded PDF file (Word doc) I get an error "The program used to create this object is AcroExch.exe. That program is either not installed on your computer, or is corrupt..."  I've tried  about everything from unchecking protected mode at startup to removing & reinstalling Adobe.  Nothing seems to fix this issue.  Any other ideas?

This is happening on Adobe reader 9, 10 & 11 with MS Word 2010 & 2013.  I've uninstalled, cleaned & reinstalled Reader 9, 10 & 11, as well as Acrobat 10 Pro & 11 Standard.  Removed "Protected mode at startup, and changed the default program for viewing from reader to Acrobat.  This will not go away.  It is affecting production at our company.
