Исключение типа "System.InvalidOperationException" произошло в System.Data.dll, но не было обработано

Question

Когда я пытаюсь загрузить файл, я получаю это исключение:

Исключение типа "System.InvalidOperationException" произошло в System.Data.dll, но не было обработано в коде пользователя.

Дополнительная информация: поставщик "Microsoft.ACE.OLEDB.12.0" не зарегистрирован на локальном компьютере.

В чем причина ошибки?
