TheHunter: COTW - AHK

[CvLd]

Hi, I'm trying to use the AHK in The Hunter:Call of the wild for sneaking without making sound. I got the code from someone else and they say it's working but not for me... I've attached an image with the code. I'm not experienced with AHK, how can I test it to see if the code is even working ? please help.
