LICENSE: USB-Dongle: C9555E: License Checkout denied...


Information in this knowledgebase article applies to:

  • Keil MDK 5
  • USB Dongle protected

SYMPTOM

I have installed Keil MDK 5 in combination with a USB Dongle protected Licensing solution.

At building my project, I see this error message:

Error: C9555E: License checkout for feature LIC0=JA... with version 5.xxx has been denied by Keil back-end. Error code: 1

CAUSE

The USB Dongle requires the Sentinel System- and Sentinel Medic driver

Either the drivers are missing, installed incorrectly, or out of date.

RESOLUTION

Redownload and reinstall the Sentinel System driver
.

Note:

Important: When running the Sentinel Protection Installer, in the InstallShield wizard, for the Sentinel System Drivers, the "Parallel Driver" must be installed (even for a USB dongle, even if there is not a parallel port on the PC). If this is not done, the Keil µVision tools may not recognize the USB dongle. See the screenshot below:
