When logged into the local admin account on Windows 7 x64 where Acrobat Standard 2015 was installed, Acrobat opens PDFs in the browser in Protected View as I have configured it. But when I logon to a domain account (accounts both with and without admin rights), the browser does not open the documents in Protected View as Reader does. We need to deploy Acrobat across the organization and have it behave consistently in Protected View. DC Customization Wizard was used to create the build. I have double-checked HKCU for conflicting entries for these settings. Enhanced Security shows as enabled on the Security tab and "Protected View" shows that it is turned on for "Files from unsafe locations" (also tried changing that value to 2 for All files without any change in the issue).
Registry:
bEnhancedSecurityStandalone = 1
bEnhancedSecurityInBrowser = 1
bProtectedMode = 1
iProtectedView =1
