Reader vs Acrobat

We’ve been running into frequent issues of people on a Terminal Server logging into Acrobat Reader and upgrading it to the full version, then when other users login they’re unable to use Reader because it’s requiring them to log in. Is there a way to prevent this or easily revert back to Reader when someone does this? How is the end user able to upgrade that without administrator permissions as well?

      Hi ​@PaulCWCS,

     

    Hope you are doing well. Sorry for the trouble with using Acrobat.

     

    This is a general scenario where, if a user with a valid license for Acrobat Pro DC, signs in to Acrobat Reader, the installation automatically upgrades to the full version of Acrobat Pro DC.

     

    Is this the use case for your people? If yes, there are very limited options we can try.

     

    Use the Adobe Customization Wizard or registry to lock Acrobat into Reader mode.

    Set this at machine level: 

    [HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Adobe\Adobe Acrobat\DC\FeatureLockDown]
    "bIsSCReducedModeEnforcedEx"=dword:00000001

     

    This forces Acrobat to always run in Reader mode and ignore user sign-in for Pro activation.

     

    If Acrobat Pro is not needed at all, you can disable sign-in by [HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Adobe\Adobe Acrobat\DC\FeatureLockDown]
    "bDisableSignIn"=dword:00000001

     

    This registry key removes the ability to sign in, also ensuring that the package does not automatically convert to Acrobat Pro from Acrobat Reader.

     

    If the state is already in affect, ask the users to sign out of the application, then clear the licensing files after closing Acrobat.

    The files can be found here:

    %LOCALAPPDATA%\Adobe\OOBE
    %APPDATA%\Adobe\Acrobat

     

    Once there, clear all the files, and the app should start up as fresh. 

     

    Let us know if this helps.

     

    Regards,

    Souvik
