Installed it into my paths (E:\BRYY\Work). Command Prompt tells me that it cannot find it, even when I do butler which. I am running windows 10.
Quoting the guide:
On Windows, follow this article to add the folder where you downloaded butler.exe to your path.
From cmd.exe, you can check that you got it right by typing "echo %PATH%" (without the quotes) then pressing enter. The result should contain "E:\BRYY\Work".
Alternatively, you can do "cd E:\BRYY\Work" and run "butler" directly from there. (If cmd.exe doesn't start in "E:", you may have to type "E:" then press enter to switch drives.)
