Я создал Windows сервис, который берет SQL Резервное копирование базы данных сервера за фиксированный интервал времени. Служба Windows отлично работает в режиме отладки, но после установки она продолжает работать, но не создает файл .bak.
Я проверил файл журнала и обнаружил
Не удается открыть базу данных "dbTest" запрашивается логином. Не удалось войти в систему.
Я использовал Windows аутентификацию для соединения.
Вот мой фрагмент кода

Вот моя строка соединения, сохраненная в app.config:

<add key ="BackupFile" value ="D:\\Backup\\"/>

</appSettings>
и содержимое установщика проекта при инициализации

Извините, я загрузил весь код, как и многие исследования, но не получилось.
Есть какие-либо необходимо внести изменения в секцию кода
