i can't install the devtools

Okay guys, I'm just beginning to learn the phalcon framework, I'm reading tutorials, but there is always one problem they all say that i need the devtools installed. I have tried many times to get it to work. But i simply can't get it to work, i have at least tried 12 times. i think where i getting it wrong is setting the paths.

I set them like this C:\xampp\php;C:\phalcon-devtools-master

I'm on windows 10

i use XAMPP Version 7.2.4, and phalcon version 3.4.2

when i run the command it saids 'phalcon' is not recognized as an internal or external command, operable program or batch file.

im getting annoyed that i cant get this to work, I hope you guys might help me


if its a path thing try moving the devtools folder to an already set and working path
