Upgrading USB key based Polar software
If you are upgrading Polar product software to v21 or later and you are using a USB dongle with version 3.25, hardware 6.1 then there is a potential for compatibility issues on a non-UK locale OS (e.g. French/US/Japanese). This is more likely to occur if you are also running other USB dongle software such as Gemalto, Revenera, Sentinel etc. You will notice that, no matter what instructions are followed, the Windows Device Manager will fail to show the Sentinel HL Key under the USB controller. If this is the case please contact us to request a new USB key with version 4.34, hardware 7.2

Prior key – version 3.25, hardware 6.1

Current key – version 4.34, hardware 7.2

Issues with USB Key and Crowdstrike™

If you find that the key is not working, even with a valid key, please go to Device Manager within Control Panel, double click the Sentinel HL Key (as shown above) and select the Driver Page, then the Driver Details button

If you see a 3rd driver called CSDeviceControl.sys then this means the device is being controlled by Crowdstrike and cannot be used until an exception has been made by your IT dept. Once this is done the USB key will then operate correctly.
