What is nRF5x_MDK_8_11_1_Keil4.msi

[studzinski]

I have installed this software several times without any result on PC. How to access an IDE??? I am really very frustrated. Since several weeks I am not able to edit, compile or run any program on nrf51822 :-(

Did you install ARM-MDK before? You have to do it. www.keil.com/.../

Yes. Keil5. It works now... Thank you!
