Autodata 345 The Hardware Information Does Not Match With Your Dongle Best May 2026

However, one of the most persistent and infuriating errors encountered by technicians and workshop owners is: This message effectively locks you out of the software. It appears even when the dongle is physically inserted into a USB port, the LED light may be on, and the drivers appear installed.

Autodata is an industry-standard technical information system used by mechanics, auto electricians, and workshops worldwide. For nearly three decades, it has provided wiring diagrams, torque settings, diagnostic trouble codes (DTCs), repair times, and component locations. In its later versions—especially Autodata 3.45 (often written as version 345)—the software uses a hardware-based licensing system involving a USB dongle (hardware key) . However, one of the most persistent and infuriating

| Cause | Description | |-------|-------------| | | The most common trigger. A new motherboard = new hardware ID. | | Fresh Windows installation | Erases the original license configuration files. | | Switching PCs | You moved the USB dongle from Workshop PC #1 to #2. | | BIOS/UEFI update | Sometimes changes the DMI/SMBIOS data that Autodata reads. | | Using a VM (Virtual Machine) | Autodata 345 detects virtualized hardware and rejects it without special configuration. | | Corrupted Sentinel HASP driver | Driver mismatch or corruption prevents correct reading of dongle ID. | | Cloned/cracked dongle | Unofficial dongles often have mismatched internal data vs. license file. | For nearly three decades, it has provided wiring

Either way, understanding why Autodata compares hardware info to your dongle is the key to solving the problem without losing your wiring diagrams and repair data for days. This article is for educational and troubleshooting purposes. Modifying Autodata’s licensing mechanisms may violate software agreements. Always prefer official support channels if purchasing a legitimate license. A new motherboard = new hardware ID

This is the method. Autodata includes a license management tool (hidden in the installation folder).
