Keil MDK-ARM 4.7 is a widely used version of the software, known for its stability and compatibility with various ARM-based devices. However, due to its popularity, the download links may become outdated, making it difficult for users to access.
It provides mature support for Cortex-M, Cortex-R4, ARM7, and ARM9 devices. Project Compatibility: Projects created in v4 use the format. While MDK v5 and v6
You can find this specific version through legacy archives or academic resources:

If your debugger isn't detected:
: The installer will prompt for a name, company, and email address to finalize the setup.
It provides excellent support for legacy , ARM9 , and early Cortex-M microcontrollers. If you are working with an older chip from STMicroelectronics (e.g., STM32F1 series), NXP (e.g., LPC2000 or LPC1700 series), or TI, this version will likely have the precise device packs and legacy drivers you need.

: If you already have a newer version of Keil installed, choose a different installation directory C:\Keil_v4 ) to avoid overwriting your current setup. Activation : The "Lite" or evaluation version is restricted to a 32KB code limit but does not require a serial number for basic use.

Many older chips will already be in the database when you select "New Project" in µVision. Project Compatibility: Projects created in v4 use the format
As the day went on, John encountered a few more issues, but with Mike's help, he was able to resolve them. By the end of the day, he had successfully downloaded, installed, and tested Keil MDK-ARM 4.7.
Installing an older version of MDK-ARM on a modern Windows PC (like Windows 10 or 11) requires a few specific steps to avoid compatibility issues.
This usually happens because MDK v4.7 does not support newer device variants (e.g., STM32G4 series). For those, you cannot use v4.7. For supported devices (STM32F1, F4, L1, etc.), verify that the .FLM file exists in C:\Keil\ARM\Flash .
: MDK 4.7 includes built-in support for many older microcontrollers. For newer chips, you might need to manually install "Software Packs," though this system was much more robust in MDK v5 and later.
