Can you also give advice on how to disable automatic updates in the Mac (macOS Sierra) version of Acrobat Pro 2017 (TLP, classic update stream, Release 2017.011.30102)?
If I try to disable automatic updates in preferences, Adobe Acrobat is asking for admin credentials to install a helper tool. If I enter the password, the checkbox is still activated. The only working solution I've found to stop automatic updates so far, is to block Adobe Acrobat Update Helper Tool in the firewall.
