Der Dienst wird auch offensichtlich korrekt installiert. Nach dem Starten des Dienstes wird die exe im Taskmanager angezeigt allerdings wird mein eingefügter Quelltext nicht ausgeführt.
Habe schon alles mögliche ausprobiert aber ich finde den Fehler einfach nicht.
Hoffe, dass ihr mir da helfen könnt den Fehler zu finden.

Danke schon mal für jegliche Hilfe.
