@zcmm: nrf.exe is a command line program. You should open it in the DOS command line window. Go to run type: "cmd" and press Enter.

@zcmm: You should type "cmd" instead of "command" when in "win+R" window. A black command line console window will appear.

Then you should navigate to the nrf.exe folder using "cd" , or you can simply paste "C:\Program Files\Nordic Semiconductor\Master Control Panel\3.9.0.6\nrf\nrf.exe" and press enter.

You can find the list of DOS commands here.
