Standartgemäß wird halt immer nach "C:\Program Files (x86)\..." installiert, die User können aber wie gesagt den Installationspfad abändern (die Registryeinträge ganz unten funktionieren nicht wirklich, sie werden zwar eingetragen aber wenn ich das Game installiere (über das eigene Setup) steht halt immer noch "Installieren" und nicht "Spielen" im AutoRun Menü da)
