Run in AppContainer

[defaultbz5ewe2gjt0a]

Hi.

Recently i noticed that the checbox "Run in AppContainer" has disappeared from the Preferences.

I need activate this for compatibility with another app, but i can't find how.

Windows version is 19043.1110

Reader version is 2021.005.20058

Any suggestion will be apreciated.

Note: sorry for my english.

Hello,

Thank you for reaching out and sorry for the trouble.

Could you please confirm if the option was removed after updating the application?

 Did you try reinstalling the application? 

Thanks,

Meenakshi

Hi.

The option has dissapeared from one day to another, not after a update.

I try to uninstall, reboot and reinstall. No luck.

I try to uninstall, reboot, use AdobeAcroCleaner, reboot and reinstall. No luck.

No further actions.

Tanks in advance.

Hi defaultbz5ewe2gjt0a ,

1. Please ensure that "Protected Mode" checkbox is checked. (Edit >> Preferences >> Security (Enhanced) >> Enable Protected Mode). 
2.  As a workaround, you may enable the preference via registry : 
   HKLM\SOFTWARE\WOW6432Node\Policies\Adobe\(productname)\(version)\FeatureLockdown
    REG_DWORD  bEnableProtectedModeAppContainer = 1
   
   1. Are you running Adobe Reader is Windows 7 compatibility mode? To check this, right-click on Acrobat Reader's icon >> Properties >> Compatibility >>  Run this program in compatibility mode for.

Hi there. Having the same issue here as well all of a sudden. Problem is that in your instructions, I have NO idea what or where you are referencing? If you're talking about settings in the Adobe Acrobat app... I can't access those if I can't open it.

In File explorer, navigate to the Acrobat.exe or AcroRdr.exe, right-click Properties.

Tab: Compatibility.  Some old installations being updated-over repeatedly, have kept the Windows 7 compatibility flag.  Newer installations do not have any compatibility settings for these EXEs

And thanks, @Shagufta for pointing to the compatibility settings issue - we have been scratching our heads for weeks trying to understand what was different about some installations.
