The Avisoft-SASLab Pro software (version 5.3.00 or higher) supports three different USB key versions:

Hardlock USB
distributed from 1999 to 2014
Sentinel HL (Hardlock Configuration or Driverless Configuration), Blue
distributed from 2015 to 2021
Sentinel HL (Driverless Configuration), Purple
distributed from 2021
Hardlock USB and Sentinel HL (Hardlock configuration, blue) require to install the Seninel HL / Hardlock USB key device driver software. This is done automatically by the Avisoft-SASLab Pro installer including Sentinel HL / Hardlock USB key device driver installation. The device driver can also be installed manually from the Thales Customer Support Portal. In order to force the installation of the legacy Hardlock device driver, the command line tool must be executed with the followong parameters: haspdinst.exe -i -ld -kp -fss

The new (purple-colored) Sentinel HL (Driverless configuration) USB keys do not require to install any driver, which means that the Avisoft-SASLab Pro installer without Sentinel HL / Hardlock USB key device driver installation can be used.

The Seninel HL / Hardlock USB key device driver software can be uninstalled using the command-line installer available from the THALES Customer Support Portal. The command line is as follows: haspdinst -r -fr -purge

Sentinel HL (Hardlock configuration, blue) keys that were purchased between 2015 and 2021 can be upgraded to a driverless configuration by executing the SASLabPro Hardlock to Driverless update procedure.


Legacy parallel port dongles are not supported anymore. These keys can be exchanged. Send an email to info@avisoft.com to arrange that.

Hardlock E-Y-E
distributed from 1993 to 1995
