To avoid dealing with this error repeatedly:

And if your workshop relies on up-to-date repair data for recent vehicle models, consider transitioning to . It eliminates the hardware dependencies and compatibility headaches of the old dongle-based system, making it a worthwhile investment for any professional workshop.

Many cracked releases include a small utility named HardwareIDChanger.exe or HDD Changer.exe . This tool allows you to to match the one hardcoded in the crack.

| Step | Action | Success Indicator | |------|--------|-------------------| | 1 | Run as administrator | Error disappears or changes | | 2 | Reinstall Sentinel drivers | Device Manager shows Sentinel device | | 3 | Disable antivirus temporarily | License generation works | | 4 | Use Windows 7 compatibility mode | Autodata launches correctly | | 5 | Regenerate license (correct UID) | License.reg applies successfully | | 6 | Disable driver signature enforcement | Unsigned driver loads | | 7 | Use VirtualBox/VMware with fixed MAC | Error no longer occurs after reboot | | 8 | Clean reinstall (after registry cleanup) | Autodata works on fresh install |

Navigate to your Autodata installation directory (usually C:\Autodata3.45 or C:\adc2 ). Look for files named install.cmd , start.cmd , or ndasbus.sys .

Autodata 3.45 relies on legacy copy-protection drivers (typically Sentinel HASP or Hardlock) designed for Windows XP or early Windows Vista. When run on a modern OS, the software attempts to query the system hardware ID to verify the license. However, due to changes in how modern Windows handles hardware abstraction and User Account Control (UAC), the driver fails to load or read the system correctly.

The error message occurs when the software's Sentinel security dongle emulator detects a change in your computer's hardware ID (UID). This breaks the binding between the generated .reg registry license file and your operating system.

To understand this error, it helps to know how Autodata 3.45 handles licensing. The software is copy-protected using a hardware security device called a (also known as a hardware key or Sentinel key). When you start Autodata, it checks for this dongle—either plugged into a USB port or connected via parallel port—and reads a unique identifier from it. The software then compares that identifier against hardware information from your computer to verify that the license is valid.

Return to your Autodata 3.45 files, open the AuDaSO folder, right-click the icon (green traffic light), and select Run as Administrator .
