First check that the host till is online and accessible. If the till is offline then that may be the cause of the error. Simply regaining a connection and rebooting the terminal may be suffice to rectify the issue. Otherwise, click the ‘home’ button (picture of a house) at the top left and then click ‘shutdown’ and ‘exit’. Now Log Off from Windows. If you are VNC’d onto the terminal then your session will disconnect. Reconnect again after a few seconds.

Log onto Windows as an Administrator. Navigate to ‘C:\PogramData\VeriFone\PAYWare Ocius Sentinel’. Delete the ‘Activation.exml’ file highlighted. 

Navigate to ‘C:\InfinityPos’ and open the file called ‘posrun.ini’. 

Note the 4 digit number highlighted. This will be the user ID and PIN that you enter later. You can close this file now.

Double click the PAYWare Ocius Sentinel shortcut on the desktop.

If you see this message, untick ‘always ask me before opening this file’ and click ‘open’.

Click ‘YES’ on the license prompt.

After the program minimizes to the system tray, double click the small icon to open it back up and then login using the 4 digit ID as both logon and pin.

Sentinel will do an update and reboot the pin pad. Please watch for when this whole process is completed. Once it is finished, Sentinel will minimise to the system tray again. You can double click the icon to open it up and it should show
‘Main Menu’ and ‘New Transaction’.

You can reboot the till and ask the staff to try it as it should be working now.
