This is probably glaringly obvious, but how do I "install" NSSM? according to the docs, I don't need to. If I wanted to use the GUI, I know that works (I've tested that) but when using cmd prompt or a batch file, it can't find it.
I know that the docs say "...preferably somewhere in your PATH", but I'm not sure where that would be. (neither of the "program files" folders work.)
set PATH
and hit ENTER. Those are the folders that are "somewhere on your PATH".Program Files (x86)
is not typically in the PATH (for a good reason). You should probably check that again.
