    EPM (Enhanced Protection Mode) IE11, Acrobat XI Pro & Windows 7 x64


      We were asked to enable this IE security control and it is causing issues with users not being able to open PDF files on some web sites.  Those employees with Reader XI have NO ISSUES so far.  Acrobat XI Pro folks are having random issues where they are not seeing the pop-up documented in Using Acrobat or Reader with Internet Explorer Enhanced Protected Mode.  Instead they see what is described in this article

      Troubleshoot viewing PDF files on the web. Some have reported seeing the pop-up, but that it does not work for all web sites. (I have only duplicated the fact that Reader never shows a pop-up and Acrobat may show a pop-up.)


      What is different between Acrobat and Reader that would make Acrobat have these issues? Why do our Readers users see no pop-ups, but Acrobat folks do?  We're a bit surprised at something that was implemented in 11.0.6 is so difficult to use in 11.0.20.


      Here is the security control from GPO and its mapping to the registry:


      Security Control:  Set 'Turn on Enhanced Protected Mode' to 'Enabled'

      Registry setting:  [HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Internet Explorer\Main]"Isolation"="PMEM"
