Autodata 345 The Hardware Information Does Not Match With Your Dongle Link

If you use (a widely used automotive diagnostic and repair information system), you may encounter Error Code 345 during installation, software startup, or when attempting to access certain features. The full message typically reads:

Check if you are receiving "Error E0226 - Sentinel key not found," which indicates the virtual USB emulator isn't active. UID shows 640000000 Restart your computer and run GetUid again as Admin. Sentinel Key Not Found If you use (a widely used automotive diagnostic

In the era of USB-C hubs and dongles, the humble USB port has become a crowded place. The Autodata security check is sensitive to port enumeration. If the dongle is plugged into a USB 3.0 hub, or if the port number has changed since installation, the software may be looking for "USB Port 1" while the dongle is now residing on "USB Port 3." To the rigid logic of Autodata 3.45, this location shift constitutes a hardware mismatch. If the dongle is plugged into a USB 3

It is a sentence that has halted productivity in thousands of garages, a digital gatekeeper that refuses to turn the key. But what exactly causes this error, and why does it persist in a program that has become a workshop staple for decades?

Autodata provides a small utility (often called DongleUpdate.exe or LicenseManager.exe ) that syncs the dongle’s internal data with your subscription.

To understand the error, one must understand the architecture of Autodata 3.45. Unlike modern cloud-based subscriptions, this older software relied on a physical security measure known as a "dongle"—a hardware key that plugs into a computer’s port (usually USB or the older parallel port).
