The HASP HL 3.25 is not actually a driver version, but a specific firmware version for legacy USB security dongles. These physical keys, originally developed by Aladdin Knowledge Systems, are used to protect expensive professional software from piracy. The Evolution of the Key

To install the driver on your 64-bit system, follow these steps: hasp hl 3.25 driver windows 10 64 bit
If you encounter issues during installation or the driver doesn't seem to work:

Thales offers newer drivers (v7.50, v8.30) that maintain backwards compatibility with many HL keys. Install the latest Sentinel HASP/LDK GUI Runtime from Thales’s website. In some cases, the application will work even if it "expects" 3.25, because the API layer is backward compatible.
Fix: Reboot into the "Disable driver signature enforcement" mode and reinstall. Consider permanently disabling Secure Boot in BIOS if this recurs. This time, the fans whirred
HASP (Hardware Against Software Piracy) keys protect software by requiring the physical USB key to be present during operation. On a 64-bit Windows 10 system, standard 32-bit legacy drivers from the Windows XP era will not function. You must use a signed, 64-bit compatible driver—often referred to as the Sentinel HASP/LDK Runtime Environment—to avoid "Error Code 33" (License Manager not running) or the "Key Not Found" error.

You can also create a scheduled task to reinstall the driver at startup (advanced scripting required).
