No, that will not work. You cannot have the page names in the same folder as you have your actual wiki files.

Installing the wiki files themselves in wiki/ is fine, but then you must choose another path for your pages. You might e.g. choose "w/" or "nothing" so that the URLs will look like http://l4d2-funs.myriapulse.com/Accueil. The latter is what you get when you follow the thread "Short URLs just will not work...".
