“Install application template”. this is not in existence

So I am trying to install a application template. In the videos it is under file then “Install application template” but not for me… Maybe that is because I only have stand alone installs. I used to install blender but that dam app roaming folder was effecting my multiple installs of blender so I never install blender I only manually create the “config” folder Could this be why.? I read that blender will not have the option of “Install application template” unless one exists OK so where is it supposed to exist ? Why doesn’t the manual say where it is supposed to exist. ? So basically how do I make it exist ?
