Not able to run the 'exercism' command in CMD during manual installation process

First of all, hello and thank you if you can help me.
I wanna learn Python and do it locally, not in the online editor. I tried the installer but it didn’t seem to work… So I went over to manual installation and followed all the steps… But when I want to verify I get this: (see picture)

Please, help me!!!

Where did you put the file and what does echo $PATH show?

(Please don’t use images to share text. Images can be much harder to read.)

I put the file in ‘C:\Users\Max\AppData\Local\Microsoft\WindowsApps’ just like I was told to. And what do you mean with ‘echo $PATH’? Is it possible to read the image or do you want me to type it out for you? Thanks for trying yo help!!!
