Hi Martin, just one quick note that I forgot to mention - when you go to edit the file when you launch the text editor that you'll use to edit it (like notepad or whatever you're using) you'll probably need to right-click it and choose "Run as administrator" to run the editor with a special privilege level, because by default recent versions of Windows have kind of locked down everything in the "Program Files" folder to avoid changes to them. But if you've run the editor with elevated privileges then it will work.
