Hi there. This program is a command-line tool and requires some basic command-line knowledge. If you don't have the prerequisite skill, you can use the helper batch files others users have created. However, there should be plenty of examples (Search the forums) on how to run this via command-line as it is pretty simple/straight forward.
Additionally, the Patreon version will soon include a user interface which will make this easier for beginners to get going.
