WFBinstaller won’t work

I’ve spent hours trying different things and the installer just keeps saying Garmin not detected. I tried the html someone made and it doesn’t show up in my files. I’ve tried to manually add a face and no matter where I put the PNG in Garmin/apps folder it just doesn’t so up. I have no idea what to do I really want to use this site but I just can’t. I just got the Fenix 8 51mm!!
