Help findingLN 8.5.1 Multi User Client on Passport

Does anyone have the part number for this client? I have downloaded several different 8.5.1 Notes clients and none of them are showing the multi-user option.

Subject: Multiuser

Afaik every client should have the Multi User Option, haven’t they? Did you try an upgrade or a clean install? did you check the command line switches?

Subject: I was doing a clean install on a new machine…

radio button for selection of multi-user install does not display. What command line switches should I be looking for?
