How (in the name of all that is good and evil) can one get Adobe Acrobat (on Windows) to stop automatically downloading and installing updates to itself?

None of the “Preferences” seem to allow any control over this.

(The cursed thing is updating itself every day and sometimes pops up dialog boxes asking me to reboot my computer. I already use a better 3rd party PDF viewer, and I’d uninstall Adobe Acrobat, except I am sure if I do that, I would jynx myself into receiving PDFs that need to be opened only in it.)
