When you receive this message, it means that the software's hardware security key is not functioning well or not working at all. Open Device manager (Start > Run > devmgmt.msc) and check if the hardware key is installed correctly. Additionally, go to Control > Uninstall a program and completely remove any installation related to the hardware security/sentinel driver then perform a new installation after you reboot the computer. If everything is performed correctly, the software should start.
