The PIPE-FLO® Viewer, PUMP-FLO®, and Customized Pump Selection Software products are licensed on each computer using a program registration system. This registration is done via unlock codes which enable the program to run indefinitely on that computer. In rare circumstances, the unlock code changes and requires repeated registrations.
This error can be fixed by having the registration process completed by a user who is logged onto the computer with Administrator privileges, and to complete the process in a single session.
If necessary, you may call our technical support department and arrange a time when an unlock code can be generated while an Administrator is present.
