Autodata 3.45 is older software designed for Windows XP or Windows 7. Running it on Windows 10 or 11 often triggers this error because the software does not have permission to access the system hardware correctly.
If this is a cracked/pirated copy of AutoData 345, the error is intentional — cracks often fail when hardware changes. In that case, there’s no legitimate fix except purchasing a licensed version.
Would you like help identifying the dongle brand (look for branding on the USB key) so you can find the correct driver or reset tool?
The "Autodata 345: the hardware information does not match with your dongle top" error is a frustrating relic of legacy copy protection. It strikes when your computer’s hardware ID no longer matches the ID stored inside your USB dongle – often after a Windows reinstall, a motherboard change, or driver corruption.
While there are several fixes (reinstalling drivers, editing the registry, applying community patches, or disabling USB power management), the most reliable long-term solutions are:
For workshop owners, time is money. Spending hours troubleshooting a 15-year-old software version may cost more than a modern subscription. But if legacy Autodata is your only option, follow the steps in this guide carefully – and always remember to back up your working system before making any changes.

This error typically occurs when the hardware ID (UID) or the registry entry for the Autodata 3.45 emulator does not align with the security dongle/license files provided with your installation Quick Solutions for "Hardware Information Does Not Match" Run as Administrator : Ensure you are running the Start Emulator Autodata 3.45 application by right-clicking and selecting Run as Administrator
. Failing to do this often prevents the software from reading the hardware ID correctly. Verify Registry Files
: The installation usually requires a unique identification number to generate a license log file. Make sure you have run the new generated registry file (e.g., Autodata 3
) to register the hardware ID with your specific installation. Regional Settings : In many cases, Autodata requires your Windows Regional Settings to be set to English (United States)
to function correctly. If your system is set to another language, the dongle check might fail. Sentinel Driver Installation : This error is often linked to the Sentinel Protection Installer Unplug any physical USB keys. Sentinel Protection Installer 7.7.1 (or the version provided with your package).
Restart your computer—this is mandatory for Windows 7, 8, and 10. Enable Test Mode
: On Windows 10/11, the emulator often requires Windows to be in
to bypass digital signature requirements for the virtual dongle driver. If "Test Mode" does not appear in the bottom-right corner of your screen after installation, the emulator will not load. Step-by-Step Recovery Process Disable UAC
: Turn off User Account Control and disable your antivirus temporarily, as it may block the emulator's drivers. Clean Previous Drivers
: If you have multiple versions of Sentinel drivers, uninstall them and run sfc /scannow
in an Administrator Command Prompt to fix corrupted system files. Regenerate UID
: Use the "Get UID" tool provided in your crack/installation folder to ensure the number matches the one used to create your Command Prompt strings to manually enable Test Mode if it isn't appearing? Autodata 3.45 Installation Guide | PDF - Scribd If this is a cracked/pirated copy of AutoData
The "hardware information does not match with your dongle" error in Autodata 3.45
usually happens because the software's security system (the Sentinel emulator) detects a change in your computer's hardware configuration or a regional setting mismatch Primary Troubleshooting Steps Change Regional Settings : A common cause is the system's locale. Set your Regional Settings to English (United States)
in the Windows Control Panel, as the emulator often requires this specific setting to validate the license. Run as Administrator
: Ensure you are running both the Autodata shortcut and the emulator program (often named or similar) by right-clicking and selecting Run as Administrator Reset Registry Settings
: If the hardware ID has shifted, you may need to clear old data. Look for a folder named RegSettings in your installation directory. Run DeleteRegSettings.reg
first, then run the appropriate registry file for your system ( RegSettings_x64.reg for 64-bit or RegSettings_x86.reg for 32-bit). Check Sentinel Drivers Device Manager and look for "Sentinel USB Key" or "Sentinel HASP".
If there are errors (like Code 45), try uninstalling the driver and scanning for hardware changes to reinstall it.
Ensure your antivirus is temporarily disabled during this process, as it can block the emulator from "spoofing" the hardware ID. Thales Group If the Problem Persists You might need to regenerate your license file . This typically involves:
Running a "GetUID" utility to obtain your current 8 or 10-digit hardware ID. Using that ID to create a new license file that matches your current machine specs. Double-clicking the new registry file to import it. Did you recently upgrade your Windows For workshop owners, time is money
or change any internal components like your RAM or hard drive?
Danger: Incorrect registry editing can break Windows. Back up your registry first.
Error 345 sometimes persists because of leftover registry entries. Delete them:
Imagine this: You have a vehicle on the lift, the customer is waiting, and you need wiring diagrams or service schedules immediately. You launch AutoData, the industry-standard vehicle diagnostic software. Instead of the main menu, you are met with a cryptic red box:
"Error 345: The hardware information does not match with your dongle."
Your heart sinks. The software refuses to open. The dongle (USB hardware key) is plugged in, the lights are flashing, but AutoData is rejecting it. You are not alone. This is one of the most common and aggravating licensing errors in the automotive repair industry.
This article provides a definitive, step-by-step guide to diagnosing and resolving the AutoData 345 hardware mismatch error, whether you are on version 9, 10, 2020, or the latest 2024/2025 releases.

If the mismatch is due to corrupted software files rather than a hardware change:
If the error appears immediately upon reinstallation, your dongle was likely paired to a different motherboard in the past and cannot be re-paired without the original license transfer tool (which is no longer supported).
