To set it up correctly create a new Folder called Clean Slate or whatever you like. Into that folder then extract the QSP player and all its accompanying folders. Into that same folder extract the Clean Slate files. So you'll have a file structure with 'Clean Slate' - or whatever you named it as the top level folder and inside that you'll have a load of sub folders called among other things Images, Audio, platforms, Sounds, styles, translations as well as numerous other files many of which are named Qt5****.
To play you then click on the Clean Slate QSP file and open it using the Qqsp. Once up and running you will see at the top left of the game four drop down menus Quest, Game, Settings and Help. On the Settings drop down ensure that in the Show/Hide part that you have Objects, Actions, Additional desc and Main Desc selected to show (ie ticked) - you can also have Captions ticked; that simply adds a label to each area so that you know which is which. You can alter the size of each area and drag and drop them into a position/layout that suits you best.
