A problem was detected with the information submitted. Please correct this issue and re-submit the form.

  • This product cannot be uninstalled using this form. Please see this article for information.

What other options are there for removing this license from this computer?

ANSWER

These free-of-charge MDK Cortex-M0 licenses cannot be uninstalled the usual way and there is no need to do so because you could not install the same license on a different PC. New licenses can be obtained with the links below at any time.

You can do the following things:

  • If you have purchased a MDK license, you just need to register it. The new LIC will overwrite the previous MDK Cortex-M0 license.
  • If you want to go back a MDK-Lite with 32KB code size limit without core or device restrictions you can modify the file C:\Keil_v5\Tools.ini with a text editor (e.g. µVision):
    [UV2]
      :
      :
    [ARM]
      :
    LIC0=11111-22222-33333-44444-55555  [Your LIC]
      :
    
    

    Please delete the line starting with 'LIC0=...' or comment it with a ';' character at the beginning of the line. After a restart of µVision, the MDK Cortex-M0 limited license must have disappeared in the File - License Management dialog.

For other users:please open a Support Ticket so support can resolve any issues with this License.
