It looks like the doc could use an update. Engineering provided some additional info which I still have to triple-verify, but I think this will be the final answer:
- Reader (per user): Set Reg pref EULA
- Reader (all users): Must set via CW or EULA_ACCEPT property
- Acrobat (per user): Can only set for browser viewing via EULAAcceptedForBrowser
- Acrobat (all users): Must set via CW or EULA_ACCEPT property
Short (tentative) answer: There is no reg setting for accepting the Acrobat EULA for all users. Use the Wizard or the cmd line property.
