Information in this knowledgebase article applies to:

  • µVision Version
  • MDK-ARM Version 5.14


When I try to execute an External Program from the Tools menu in µVision, the following error occurs:

Error: failed to execute C:\Windows\externalprogram.exe


This error occurs in µVision version V5.14.0.0 when the RUN INDEPENDENT flag is selected in the dialog Tools - Customize Tools Menu.


You may download the ZIP file attached to this article and extract its content to the folder C:\Keil_v5\UV4. This will update the UV4.exe file to version Do not apply this patch to any other MDK version than 5.14!
