I've been searching for answers on this for 2 days now. My Acrobat Reader DC app won't launch, as in after I click the executable it loads for a second then nothing. Nothing in the task manager, nothing at all. It just won't launch, Tried reinstalling, restarting computer, nothing happens. Any help would be appreciated, thanks.

I do not know how to modify my registries.

Thank you,

Hello teddyd40786348 and JohnAGlyden,

Sorry for the inconvenience caused.

Please create the following registry and verify:

At the following registry key [HKEY_CURRENT_USER\Software\Adobe\Acrobat Reader\DC\Privileged]

create dword bEnableProtectedModeAppContainer and make it value 0

Please relaunch your Reader and verify if its able to launch now.

Confirm to me once you experiment this out.

This is a security preference, so ideally it should be enabled to protect Reader from exploits and vulnerabilities.

If your are able to launch Reader after disabling the registry value, I would like to get to the root cause of this issue after enabling the registry back . It could be due to some configuration in your system or some antivirus software conflicting.

Thanks,

Shakti K

    That worked. Thank y’all


    Hi teddyd40786348,

    Thanks for testing this out.

    As Run in App container preference which we made OFF by the registry key option is a critical feature from security perspective, so Run in App Container should be made ON, so that this issue can be debug and fixed.

    Can you please provide me with the process monitor logs in the case where Reader was not able to launch for you.

    Steps to follow:

    1. Launch Reader.
    2. Goto Edit->Preferences->Security(Enhanced)
    3. Check the checkbox Run in App Container and press OK to the preference dialog.
    4. Close Reader. View that the registry key bEnableProtectedModeAppContainer is set to 1 in this case.
    5. Open process monitor . Process monitor can be downloaded from Process Monitor - Windows Sysinternals | Microsoft Docs
    6. Now try launch Reader . You will encounter the error as earlier faced by you.
    7. Save the procmon logs as .pml file and send it across to me.

    I have private messaged you my email details.

    Thanks,

    Shakti K
