Can't Seem To Add Make Pkg By Right-Clicking

I'm having issues getting make pkg to appear by right clicking on a folder. I'm on windows 10 btw. I have this on my old laptop, but I can't seem to remember how to do it on the new one. I think it's the .bat file, but it doesn't seem to work on windows 10. thanks.

edit: alright, it says "cannot find registry key." these registry values may only be for windows 7.
