I have a N_m3u8DL-RE problem in my CMD.

So i have downloaded N_m3u8DL-RE,mp4decrypt,ffmpeg and i am trying to download DRM videos with the help of keys. I have found how to get the key but the problem for me starts at the CMD programm.
In the first picture it shows where i have my downloaded .exes , in the second my CMD and the problem it shows me, and the third the actual problem with the N_m3u8DL-RE

use:

./N_m3u8DL-RE --key ......

instead of

N_m3u8DL-RE --key ......

use:

./N_m3u8DL-RE --key ......

instead of

N_m3u8DL-RE --key ......

I tried it in CMD and it said " '.' is not recognized as an internal or external command,operable program or batch file."
So is it possible that none of my commands work for some reason?

I think the actual problem is the first line in the screenshot.

When i run N_m3u8DL-RE.exe on its own and click on it before it is run through it shows: "the required argument missing for command: 'N_m3u8DL-RE' ".
I think this is the reason why it doesn't work on CMD, but is there anything i can so that the command isn't missing and i can call it up in CMD?
