Right-click the time display on your taskbar and select .

Note the 8-digit (32-bit) or 10-digit (64-bit) code that appears. Add the executable file for the Sentinel License

If the problem persists after trying the steps above, your dongle may have internal memory corruption, requiring a replacement unit from your AutoData distributor.

If your computer's internal configuration has changed, the software license will no longer recognize it. You must generate a matching license profile:

Click , choose Folder , and target your main installation root (typically C:\Autodata or C:\Program Files (x86)\Autodata ).

For detailed visual steps on resolving specific "Sentinel Key Not Found" or "Runtime Error 217" issues, you can refer to troubleshooting guides on

The Sentinel or HASP driver responsible for reading the USB dongle may have crashed or become corrupted. Right-click the time display on your taskbar and select

You recently replaced a motherboard, CPU, or hard drive.

For automotive professionals relying on Autodata for technical data, wiring diagrams, and repair information, encountering a dongle error can grind productivity to a halt. One of the most frustrating errors, particularly with and similar versions, is the message: "The hardware information does not match with your dongle" or similar Sentinel key mismatch errors.

Check the box at the bottom for . Click Apply and launch the program. 3. Regenerate the Registry License File

If you cannot access the old computer (e.g., it crashed), you may need Autodata support to remotely reset your license. Most vendors allow a small number of forced resets per year.

Several everyday computer changes or technical glitches can inadvertently trigger this security alert:

This error is rarely a sign of a faulty dongle—most often, it is triggered by legitimate hardware changes. Do not attempt to use “patcher” tools or crack the software; they will fail against modern dongle encryption and may introduce malware. Always rely on the official rehosting process from AutoData.

By following this guide systematically—starting with physical checks, moving to driver reinstallations, then using the license management tools, and finally contacting support—you will minimize downtime. Remember: a proactive deactivation before any major PC change is worth an hour of reactive troubleshooting.
