Unplug the hardware security key (USB dongle) and plug it securely into a different USB port. Common Causes and Troubleshooting Steps 1

Move the dongle from a USB hub directly into a port on the computer chassis. Avoid USB 3.0 (blue) ports if you are using older legacy dongles; use USB 2.0 (black) ports instead.

If you have tried the steps above and still see the "Valid license not found" message, your security key may be physically damaged or your subscription may have expired. At this point, you should contact with your Key ID number ready.

Ensure the LED indicator light on the dongle is on. A flashing or dead light points to a hardware failure or driver issue.
