Zugriff verweigert, wenn WPF-Anwendung gestartet wird

Question

Wir haben ein Problem beim Starten von WPF-Anwendungen, die über ClickOnce verteilt wurden. Benutzer, bei denen dieses Problem vor kurzem auf .NET 4.6.2 aktualisiert wurde, werden unter 4.5.2 erstellt und kompiliert. Aber es installiert ok, wie Sie aus dem Protokoll sehen können, das ist also nicht das Problem. Benutzer von Windows laufen 7.
Hier ist der Fehler, den wir bekamen:

Irgendwelche Ideen auf, was ist das über und wie man es beheben? Das Entfernen und Installieren der Anwendung hilft nicht, und das Zurücksetzen auf 4.5.2 hilft auch nicht.

Answer 1

Das Problem war, dass Antivirus-Software die Anwendung aus irgendeinem Grund blockiert (zwei separate Programme, Kaspersky und Avast). Nach dem Hinzufügen unserer App zu einer Whitelist ist das Problem verschwunden.
