QUESTION

During the compilation of my project I see an error message like:

Error: C9555E: Failed to check out a license.MISSING DEVICE (R003(0): SECURITY KEY NOT FOUND)
  • Is my connected USB Dongle broken and how can I get a replacement?
  • Or are there any other reasons known that end up with this error messages?

ANSWER

If your license is protected by a USB-Dongle:

If your license is not protected by a USB-Dongle:

  • If your product is the MDK-ARM Cortex-M only edition and you try to install a version older than V4.60 this error also rises. This product line was introduced with V4.60. The former MDK-ARM Standard- as well as the MDK-ARM Professional-licenses would work with MDK-versions before 4.60.
