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.)
Place the nssm.exe file in a folder, which is already on your PATH variable
Use echo %PATH% or set PATH on the CLI to find out the folders.
OR
Place into C:\Programs\nssm and then add this folder to your PATH env variable:
setx PATH "%PATH%;C:\Programs\nssm" /M
