The PRS PowerPoint Add-in must be registered on the system on which it is installed. Registration of the PRS Add-in must be done by a user with Administrator privileges. As the PRS installation must be done by an Administrator, the PRS PowerPoint Add-in is automatically registered during installation, and the registration of the Add-in applies to all future logins of this user.
All other users who login to this system must register using the Register PowerPoint Add-in option from the Start/Programs/InterWrite PRS menu.
