SYMPTOM

After uninstalling a license ID code (LIC),compiling a project fails. The Build Output window reports the following error message:

Error: C9555E: License checkout for feature LIC0=XX...-.....-..... with
       version 5.0xxxxxx has been denied by Keil back-end. Error code: 1

No other changes were made to the computer, application or IDE.

RESOLUTION

Try one ofthe following:

  1. Revert to MDK-Lite: To downgrade to the MDK-Lite edition with 32KB code size limit:
    • modify the file C:\Keil_v5\TOOLS.ini inside a text editor (e.g. µVision):
      [UV2]
        :
        :
      [ARM]
        :
      LIC0=TRNxx-xxxxx-xxxxx-xxxxx-xxxxx-xxxxx-xxxxx  [Your Uninstall-LIC]
        :
      
      
    • Delete the line starting with LIC0=TRN... or comment it with a ';' character at the beginning of the line.
    • Save and close this file.
    • After a restart of µVision, the Uninstalled license will disappear in the File -> License Management dialog and MDK-Lite will be shown instead.
  2. Re-license If you have already purchased an MDK product, re-license the tools. A new LIC can overwrite the previous license code.
  3. Switch to a new license: If you want to confirm product information, contact Keil technical support. After confirming some information with you, they can discuss the status of a product. Providing a LIC or PSN (Product Serial Number) helps speed up the process.

After taking corrective actions, try building the current project again - the license errors should disappear.
