While I was trying to set up butler, I ran into this issue of butler not being recognized as a command while trying to run "butler login". As you can see in the picture, butler is installed and running in the background. Does anyone know why I have this problem?

Sorry. How do you know this?

Butler is installed and running in the background.

As far as I remember, Butler is NOT installed and doesn't run in the background.

If you want to use Butler as a command from any path on your PC, then you must add the Butler folder path to your operating system's Path Environment Variable.

If you don't add it to the Path Environment Variable, then your terminal must be in the same folder where you downloaded the Butler executable.

EDIT:

Please review these steps again:

Adding butler to your path

Adding an executable to your path allows you to launch it from anywhere, no matter which directory you're currently in.

On Windows

Follow this article to add the folder where you downloaded butler.exe to your path.

Alternatively, Windows will look into the current working directory when looking for commands

and

First run

To make sure butler is installed properly, open a terminal (cmd.exe on Windows), and type the following command:

butler -V

(that's a capital V, casing matters)

It should print something like that:

Oh, thanks for pointing that out. When I saw the change from human-friendly to automation-friendly instructions, I thought that meant that I was done with that page. I thought that just because the itch app said it was running that it was running.
