Starting the program the following message is shown:
Unable to access Sentinel Run-time environment (H0033)
The problem is usually caused by a Windows update that conflicts with the security key drivers.
Simply reinstalling the protection key drivers will resolve the error: a copy of these drivers can be found from our Download Center.
Please follow this procedure:
Phisically disconnect all the USB protection keys from the computer, including those for other software
Uninstall "Sentinel runtime" from the Control Panel
Restart the computer
Reinstall the drivers downloaded from the link above
Reconnect the USB keys to the computer
Restart the software
If a network license is used (red USB dongle), it may be necessary to update the drivers on the server to which the USB key is connected to.
