How to disable Adobe Sign in prompt

On our session host servers, Adobe Acrobat Reader (free version) auto updated to 2026.001.21367.  Several users are now being prompted to log into Adobe.  If they cancel, the program closes.  Users should not need credentials to use a free program.  I’ve had to change their default reader to be Edge just so they can continue to work.

I’ve tried the following:!--startfragment>

Disabled new acrobat

To fix Adobe Reader freezing, immediately try disabling Protected Mode in Edit > Preferences > Security (Enhanced) and unchecking "Enable Protected Mode at startup".

Edit > Preferences > General 'Messages from/to Adobe' uncheck 'Show me messages when launch Adobe Acrobat'

This is a common fix, but ‘Sync preferences’ is no longer an option in this latest version.

Edit > Preferences 

Select Adobe Online Services in the categories list.

Uncheck the option Sync preferences across devices and document services.

I can’t imagine uninstalling/reinstalling will fix it, since it’s the latest version, and Adobe doesn’t realize that not all of its products require logins.  I’m tired of dealing with Adobe hijacking my users when all they need to do is open a simple pdf.  Please tell me there’s a fix.
