If you cannot obtain MDK 4.7 legally, but need to compile a project originally written for it, consider these alternatives:
Keil MDK-ARM version 4.7 (specifically 4.74) is a legacy version of the Microcontroller Development Kit widely used for ARM Cortex-M based microcontrollers. While the industry has largely shifted to or the newer Keil Studio , many engineers still require v4.7 for maintaining older projects or specific legacy hardware.
