Windows installer service cannot be accessed

Обновлено 16.12.2016

Добрый день уважаемые читатели блога и гости канала, в прошлый раз мы с вами победили ошибку: запуск этого устройства невозможен. (код 10), там у нас были проблемы с установкой оборудования, сегодня же разберем проблему с установкой или удалением программы в десятке. Ситуация такая у вас есть ОС windows 10 или предыдущая редакция, вы пытаетесь установить, например обновление Skype или же удалить какую-то программу с вашего ПК, но в процессе получаете ошибка windows 1719: windows installer service could not be accessed, и в итоге установка или удаление завершается неудачно. Ниже я вам расскажу причину данной проблемы, и мы ее победим на сто процентов.

Что такое Windows installer

Windows installer это специальная служба операционной системы Windows, благодаря которой вы можете устанавливать или удалять приложения в ОС.

Причины ошибки windows 1719

Для начала нужно понять, от чего лечить систему, я вам уже озвучил выше, что windows installer service could not be accessed я получал при установке skype и при удалении программы КриптоПРО, но могу точно вам сказать, что выскочит она везде и при любой попытке инсталляции в Windows 10. Вот как это выглядит.

Еще ошибка 1719 может иметь формулировку Служба установщика Windows недоступна в Windows 10, я такое ловил при установке драйверов рутокен. Нечто похожее мы с вами уже видели, когда Служба установщика Windows недоступна в безопасном режиме

В любом случае проблему устранить нужно, так как мы потеряли возможность, что либо ставить или удалять в Windows 10.

Методы решения ошибки windows 1719

И так давайте разбираться как нам с вами устранить windows installer service could not be accessed. Contact your support personnel to verify that it is property registered and enabled и Служба установщика Windows недоступна в Windows 10.

• Включение службы установщика Windows в ручную > да для начала попробуйте удостовериться, что сервис windows installer включен. Сделать это просто нажимаем клавиши WIN+R и вводим services.msc (другие команды меню выполнить читайте по ссылке).

Находим службу Установщик Winows (Windows Installer), щелкаем по ней правым кликом мыши и выбираем из контекстного меню пункт свойства.

Ее принудительный запуск, в некоторых случаях поможет вам избежать ошибку 1719 в windows 10.

В итоге вы должны получить запущенный сервис, после чего смело закрываем оснастку и пробуем проделать процедуру установки или удаления нужно программы, у меня это КриптоПРО. В моем случае это не помогло, идем дальше.

Если вы внимательный пользователь, то можете обратить внимание, что изменить тип запуска у службы у вас не получиться, это еще идет от времен Windows 8.1, а вот в семерке поменять можно, ради эксперимента выставите в ней автоматический тип запуска и перезагрузитесь, проверьте отсутствие ошибки 1719.

• Итак, если первый метод вам не помог и у вас выскакивает Ошибка 1719. «Не удалось получить доступ к службе установщика Windows», то попробуем произвести процедуру восстановления компонентов системы, для этого откройте командную строку от имени администратора

и введите:

Если вы получите поврежденные компоненты, то ваша система постарается их восстановить автоматически.

• Если ошибок при сканировании компонентов вы не обнаружили, то проверьте присутствие файла msiexec.exe по путям, описанным ниже, если его там не будет, то вы логично будите постоянно получать: error 1719 windows installer service could not be accessed. Если файла там нет, то скопируйте его с другой системы, либо можете просто переустановить Windows Installer, он спокойно скачивается в интернете.

• Иногда бывают случаи, что сам файл msiexec.exe находится в нужно расположении, но все равно получаете ошибку windows installer service could not be accessed, и причина в том, что библиотека не зарегистрирована. Давайте я покажу как это сделать. Снова запускаете командную строку от имени администратора, это обязательно и делаете вот, что:

После ручной регистрации сервиса Windows Installer, можете проверять исправилась ли ошибка: error 1719 windows installer service could not be accessed, мне к сожалению, не помогло, но я не расстроился и стал искать дальше.

• Что еще может помочь если вы получаете, что Служба установщика Windows недоступна или windows installer service could not be accessed, как ни странно, при попытке удалить КриптоПРО, он сам может выступать проблемой как для себя, так и для других программ, ломая службу msiexec.exe. Решением, является правка одного ключа реестра, я покажу, что именно нужно исправить и как обычно по традиции выложу ссылку на готовый ключ, чтобы вам было удобно.

Нажимаем WIN+R и вводим regedit, у вас откроется редактор реестра.

Переходим в раздел реестра и исправляем ключ Force с 0 на 1.

После чего перезагружаемся, и о чудо мне это помогло я больше не увидел ни error 1719 windows installer service could not be accessed, ни Служба установщика Windows недоступна, я спокойно смог удалить программу КриптоПРО и больше этой проблемы у меня не возникало, надеюсь вам помогла данная статья и вы смогли устранить очередной глюк Windows 10.

Windows Installer Not Working FAQ

Служба установщика Windows (она же Windows Installer), является одним из основных компонентов операционной системы, необходимых для установки программного обеспечения. Windows Installer используют все программы, созданные для Windows, соответственно, если в процессе установки программы эта служба не отвечает или не доступна, установка завершится неудачей.

Как правило, в таких случаях на дисплеях пользователей появляется следующее сообщение об ошибке:

Ошибка 1719. Не удалось получить доступ к службе установщика Windows. Возможно, установщик Windows не установлен. Обратитесь за помощью в службу поддержки.

Так эта ошибка выглядит на английском языке:

Один из возможных способов решения этой проблемы заключается в использовании средства сканирования системных файлов. Чтобы его запустить, откройте командную строку с правами администратора, введите команду sfc /scannow, нажмите Enter и дождитесь завершения проверки файлов.

Если sfc /scannow не помог и программы по-прежнему не устанавливаются, можно попробовать несколько других вариантов, которые совокупно должны помочь устранить проблему.

1. Убедитесь, что служба установщика Windows запущена

Нажмите  + R, введите services.msc и нажмите OK.

В окне «Службы» прокрутите вниз и найдите службу Windows Installer. Вполне возможно, что она просто отключена, отсюда и ошибка 1719.

Двойным щелчком мыши откройте окно свойств службы и измените тип запуска с «Отключена» на «Вручную» или «Автоматически». Затем нажмите «Запустить» и примените изменения.

Закройте окно «Службы» и проверьте состояние проблемы. Если ошибка все еще имеет место быть, приступайте к выполнению следующего шага.

2. Перерегистрация службы установщика Windows

В большинстве случаев достаточно выполнить перечисленные выше шаги, но иногда также может потребоваться повторная регистрация службы установщика Windows.

Итак, нажмите  + R, введите MSIEXEC /UNREGISTER и нажмите OK. Ничего страшного, если после выполнения команды на экране ничего не произойдет.

Опять-таки, нажмите  + R и введите MSIEXEC /REGSERVER.

Эта команда завершит перерегистрацию службы установщика, а вместе с этим должна решиться и ваша проблема. Если нет, тогда попробуйте еще кое-что.

3. Пробуем через реестр

Нажмите  + R, введите regedit и нажмите OK.

В окне редактора реестра перейдите в HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesmsiserver.

Проверьте значение параметра ImagePath. Должно быть так, как на скриншоте ниже; при необходимости измените путь и запустите службу установщика Windows через services.msc.

В 64-разрядных версиях Windows есть еще один параметр – WOW64, который следует проверить.

Обратите внимание на его значение – если 1, это и является причиной проблемы.

Двойным щелчком мыши откройте свойства параметра WOW64 и поменяйте значение на 0.

Далее просто перезагрузите машину. После этого ошибка 1719 должна исчезнуть.

Отличного Вам дня!
