Hey there,
butler is a command-line application, so you'll need to run it from the command line. The official guide explains everything in (hopefully) easy steps: https://itch.io/docs/butler/in...
Try following it page by page, and if you still have issues feel free to post your questions here!
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.)
