Activation of 7-day MDK-Professional trial license

Learning Platform

MDK-Lite has a built-in free seven day trial license of MDK-Professional. To give the user the flexibility to choose the evaluation period himself, this license needs to be activated manually. The following instructions explain the required steps.


  1. Open µVision in 'Administrator' mode. This is required when adding/removing/changing licenses in the License Manager.
  2. In µVision, go to File --> License Management.... A new window opens:

  3. Go to License Management

  4. Click on Evaluate MDK Professional. Another window comes up:

  5. Start Evaluation

  6. Click on Start MDK Professional Evaluation for 7 Days.

Note: If you have a Product Serial Number (PSN) for another edition of MDK available, refer to Activate a license.

Note Note

  • Every MDK installer looses the ability to install the trial license one year after original publishing.
  • Unfortunately, the 7-day MDK pro evaluation did not work with the compiler versions ARMCC 5.0.6u5 and ARMCLANG 6.7 which are part of MDK V5.24 preview and MDK V5.24a. Install MDKv5.25 preview instead.
