The Citect Installation is not recognising the USB key at Run Time. CiuSafe can see the key. Able to run with a network licence.

Sentinel Driver and CiuSafe are all up to date. Checked the sentinel driver status and found out that it is stopped. When attempting to start, it gives the error of "The dependency service or group failed to start"

The problem is due to CitectSCADA running on particular, DELL laptop (may happen to other laptop too) which is undocked. The sentinel driver has dependency on parallel port by default and the problem will not occur if CitectSCADA is running on Desktop or docked laptop.


Use the following method to disable and remove the dependency on the parallel port so that the Sentinel driver only uses the USB hardware key.

  1. Start the Sentinel System Driver configuration application. Located at C:\Program Files\Common Files\SafeNet Sentinel\Sentinel System Driver\SetupSysDriver.exe.
  2. Click the Configure Driver button.
  3. In the Ports table, select the line where the port is 'ECP', and click the Edit button.
  4. On the Configure Port dialog box, select the No radio button for 'Use this port?'. Click OK to save the changes.
  5. Click OK on the Sentinel Driver dialog box and close the Sentinel System Driver.
  6. Navigate to Start > Run, type regedit and click OK.
