Once restarted, plug in the HASP HL dongle. Open Device Manager and look under "Universal Serial Bus devices" or "SafeNet USB Key." If the driver is working, you should see the device without any yellow warning icons. For advanced verification, you can use the Sentinel HASP Admin Control Center (accessible via localhost:1947 in a web browser) if included with the driver.

The most reliable source for any HASP driver is the official manufacturer. Since Thales now manages the legacy SafeNet products, the recommended starting point is the Thales support portal. However, version 3.25 is an older release no longer prominently featured on the main download page. Users can typically find archived versions under "Legacy Products" or by searching the Thales knowledge base for "HASP HL 3.25." If the official site does not host this specific version, trusted third-party repositories like driver.gemalto.com (a former SafeNet domain) or the Internet Archive may have copies. Always verify the digital signature of any downloaded installer to avoid malware.

Follow the on-screen prompts. The installer will stop any related services, copy system files, and register the driver. Do not interrupt the process. After completion, restart your computer even if not prompted—this ensures the driver loads correctly at boot.
