GENERAL: MDK-ARM on Windows 8 or 10: "IDE Has Stopped Working" Error

Information in this knowledgebase article applies to:

  • MDK_ARM: any version


An old version of MDK-ARM is causing problems when started under Windows 8x or Windows 10, i.e. After starting the Keil IDE, the program freezes and a "...IDE has stopped working" error dialog appears.


Windows 8 was published October 2012 and Windows 10 in July 2015. Any version of the Keil tools released earlier than those dates is not guaranteed to be compatible with that Windows version.


Update MDK-ARM to version 4.50 or later.

Note: Any µVision version older than v4.50 is not recommended for use with Windows 8x or Windows 10. MDK-ARM V5.16a was tested with Windows 10, see MDK-ARM System Requirements.
