1. What the message means

• The system has compared stored or expected hardware identifiers (IDs) — such as part numbers, serial numbers, hardware revision codes, calibration IDs, VIN-linked module IDs, or hardware UUIDs — against the information presented by a linked resource (a firmware image, configuration link, CAN network response, or database entry).
• A mismatch means at least one expected hardware field differs from the linked source. This can block firmware updates, configuration application, or operation until resolved.

Autodata 345 reports an error stating: "the hardware information does not match with link." This document explains likely causes, diagnostic steps, and step-by-step remediation actions to resolve the mismatch. It is written to be vendor-agnostic and applicable to embedded systems, ECUs, vehicle telematics modules, or other hardware that uses firmware/software linking to hardware identifiers.

2. Corrupted or Outdated Drivers for the Hardware Key

The USB dongle relies on specific drivers (often from SafeNet, Sentinel, or HASP). If Windows updates automatically replace or corrupt these drivers, the software cannot read the dongle correctly.

7. Server-Side Deactivation (Online Validation)
