Setup-Assistent und Update-Abfrage bei jedem Start
Die heruntergeladene Datei ist ein Setup: Sprache, Ordner (nur ohne Admin-Rechte beschreibbar), Verknuepfungen, Fortschritt, Fertig-Seite; Ordner steht in der Registry. Deinstallieren loescht im gewaehlten Ordner nur die eigenen Dateien. Beim Start fragt der Launcher nach neuen Updates (Launcher und Mod). Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
