LICENSE: 'Check Out' button is disabled for FlexNet License

Information in this knowledgebase article applies to:

  • MDK Version 5.00 till MDK Version 5.10
  • MDK Version 4.60 till MDK Version 4.73


When the support period of a FlexNet license is expired but the MDK version was released within the support period, µVision disables the 'Check Out ...' button in the license management dialog by mistake. It is not possible to check-out/borrow a license from the license server.


Please update to MDK version 4.74 or MDK version 5.11 (or later), to solve this problem.

Please note that if an MDK version is installed which was released after the support end of the FlexNet license, the 'Check Out ...' button is disabled intentionally. If the compilation tools are newer than the support end of the license, the tools cannot be used anyway.
