I have seen numerous discussions, where the automatic update of Acrobat Reader DC causes errors, problems or difficulties. Why does Adobe not incorporate the possibility to manually disable updates of Acrobat Reader DC again? Most users are well educated, if they disable automatic updates IMHO and know what they do.
The majority of products offer such a function. Let the users decide themselves!
Could you please let us know what issue you are facing with the Reader DC update? Adobe Acrobat Reader is set up for automatic updates by default. It does not provide any UI option in the preferences to control this setting.
