Why does an Omni Password feature fail to work?

Why does an Omni Password feature fail to work? There are three main reasons for an Omni Password feature not to work: 1) It has not been setup correctly, but as the user interface is very simple, it is fairly unlikely; 2) The Omni Tools dictionary is not installed on all workstations, Omni Password can only work on a workstation when it is actually installed on that workstation; 3) The feature has been disabled for the system, company, user or user and company using the Omni Tools Control Panel (Cards >> Omni Tools >> Control Panel).
