Protection key software cannot be started


When I try to open a database, I receive the error message "The protection key software cannot be started".


This error is displayed when the dongle drivers are not (properly) installed. Try uninstalling the drivers from the computer and reinstall them again.

Step 1: Uninstall the drivers

  • Remove the dongle from the computer.
  • Click Start, click Control panel, then double-click "Add or remove programs" (Windows XP) or double-click "Programs and Features" (Windows Vista), or select "Uninstall a program" (Windows 7).
  • Select the Sentinel program from the list and uninstall the program.

Step 2: Install the drivers

  • You can download and install the latest Sentinel drivers from the Sentinel website. Choose the Windows operating system option 'Sentinel System Driver Installer for Sentinel SuperPro, UltraPro & SHK'. Make sure you have sufficient privileges to install the drivers on the computer.
  • After installation, attach the dongle to the computer again.
  • Run the check SN tool. If the serial number of the dongle is displayed, the dongle is recognized.
