If you are seeing error message related to the Windows Installer Service (e.g., Windows Installer Service could not be started), you should check to see if the service has stopped.
You will need to start the service if it has stopped. If it’s already started, you could try stopping it and then starting it again.
You can restart the Windows Installer Service using the Services Manager or from the Task Manager.
Using Windows Services Manager
- Press Win + R and type in
services.mscto launch Windows Services Manager. - Scroll to Windows Installer and right-click on it, click Properties.
- Look for status under Service status
- Click on Stop then click on Start. (If the service status already says “Stopped,” click on Start.)
- Try installing/uninstalling the application again.
Restart the Windows Installer Using the Task Manager
The Windows Installer service can also be started/restarted from the Task Manager.
- Press Ctrl + Shift + Esc to launch the task manager.
- Switch to the Services tab and scroll to find msiserver. This service is the Windows Installer service.
- Right-click on msiserver and select Start. If the status is Running already, you can instead select Restart.
This should start the Windows Installer service. Now try installing or uninstalling applications to see if the issue has been fixed.
Re-register the Windows Installer
Another attempt is you can try re-registering the Windows Installer and see if this fixes the issue.
- Press Win + R and type in cmd to launch the command prompt.
- At the prompt, type in:
msiexec /unregisterand press enter.. - Next, type in
msiexec /regserverand press enter.
- Try and see if you can install/uninstall now.
Reset the Installer Service in the Registry
Microsoft has provided a way to modify your registry for this particular case, which resets the installer configurations. This will hopefully solve your issue with the installer not working.
- Press Win + R and type in
notepadto launch the notepad. - Copy and paste the following into the notepad:

- Save the file as
WindowsInstaller.reg. Be sure to select “All file types” in the save as window.
- Right click on the saved file and select Merge. (Windows 11 users: Right-click > Show more options > Merge)
- Restart the computer.
Remove the Earlier Version of the Program You Want to Install
Sometimes you might run into problems installing a program if an earlier version of the program is already installed in the system. In such case, you should first remove the earlier installation then try to install the newer version.
- Press Win + R and type in
control panelto launch the Control Panel. - Under Programs, click on Uninstall a program.
- Scroll to the program in the list and right-click on it. Then select Uninstall.
- Restart the computer and try to install the newer version now.
Delete Duplicate msiexec.exe File
If a duplicate msiexec.exe file exists, it might be causing a conflict with a copy of itself. In such case, you can delete the duplicate file to resolve the issue.
- Press Win + R and type in
%windir%\SYSWOW64. For 32-bit systems, the path is%windir%\system32. - Locate
msiexec.exeand see if there is a duplicate entry. - Delete the duplicate file.
That should have resolved your problem. Check for yourself by trying to install the application.
Windows Installer is a core service that manages the installation of everything in Windows, including apps, features, and many other things. If it breaks, you will be stuck with new installations and even app upgrades.
In this post, we will share a list of error codes and their solutions, some pointing to our existing solution, and how to solve them.
1] Run Program Install & Uninstall Troubleshooter
The first thing we would suggest is to run the Program Install and Uninstall Troubleshooter to repair issues that block program installation or removal because of corrupted registry keys. This program will fix corrupted registry keys on 64-bit operating systems, which control the update data, problems that prevent existing programs from being completely uninstalled or updated, and problems that block you from uninstalling a program through Add or Remove Programs (or Programs and Features) in Control Panel
2] Start the Windows Installer Service
In the Run prompt, type MSIExec, and then press Enter.
If you get the Windows Installer window which tells you everything about MSIExec, then it’s all good.
If you get an error, you might have to start it manually.
Right-click on the taskbar, and select Task Manager. Switch to Services, and look for msiserver. Start it.
You can also run services.msc to open Windows Services and go to Windows Installer, and restart it.
3] Windows Installer Service could not be accessed
You may see the message Windows Installer Service could not be accessed. This usually happens if the Windows Installer Engine is corrupted, installed incorrectly, or disabled. You will need to fix either the corruption or fix the configuration or enable it. The linked post also solves the issue where the Windows Installer service could not start, and gives the message as Error 5, Access is denied.
4] There is a problem with this Windows Installer package
If the Windows Installer package faces unstable network access during the uninstallation or installation process, sometimes, the error might appear if you fail to complete the process successfully. The error message might go like “There is a problem with this Windows Installer package. A program required for this install to complete could not be run. Contact your support personnel or package vendor.”
5] Windows Installer keeps popping up
Usually, the Windows Installer or msiexec.exe runs in the background. You can check in the Task Manager under the list of processes that are running. However, if you see it constantly running, and the Windows Installer keeps popping up, it means it is stuck. It is possible that an installation is not able to complete, and this happens as a result.
Read: Windows Installer Service missing.
6] Installation Package could not be opened
If you are not able to install software that you just downloaded from the internet, and it keeps throwing the error message “Installation Package could not be opened“, then it’s probably a security issue. Windows many a time blocks applications you download from the internet as it does not trust them. You may have to unblock it or disable your antivirus to fix it.
7] Re-register Windows Installer service
If nothing works, the best option in our experience is to re-register the Windows Installer service. The reason why it works great because it fixes registry issues as well, and gets the basic settings ready again.
Launch the command prompt with admin privileges. Type the following commands and hit Enter after each one.
%windir%\system32\msiexec.exe /unregister %windir%\system32\msiexec.exe /regserver %windir%\syswow64\msiexec.exe /unregister %windir%\syswow64\msiexec.exe /regserver
Close the command prompt, save all your work, and restart your computer.
Check if you are facing Windows Installer issues.
Windows OS maintains a Windows Installer cache. Any files you install are temporarily extracted here and then installed on the PC. If you are deleting files from here manually or during installation or any other program is doing that, you will get an error.
How to check Windows Installer version?
To check the version of Windows Installer on your computer, open the Run box, type msiexec -? and hit Enter. You will see the version mentioned at the top.
How do I fix a corrupted Windows installer?
Since the Windows Installer is a system file, the best way to repair or fix a corrupted Windows Installer is by running the built-in System File Checker. Alternatively, you could search for the latest version of Windows Installer file on the Microsoft.com website and download it from there,

Эта инструкция должна помочь, если при установке какой-либо программы в Windows 7, Windows 10 или 8.1 вы видите одно из следующих сообщений об ошибке:
- Служба установщика Windows 7 недоступна
- Не удалось получить доступ к службе установщика Windows. Это может произойти, если неверно установлен установщик Windows
- Не удалось получить доступ к службе установщика Windows Installer
- Возможно, не установлен Windows Installer
По порядку разберем все шаги, которые помогут исправить эту ошибку в Windows. См. также: какие службы можно отключить для оптимизации работы.
1. Проверить, запущена ли служба установщика Windows и есть ли она вообще
Откройте список служб Windows 7, 8.1 или Windows 10, для этого, нажмите клавиши Win + R и в появившемся окне «Выполнить» введите команду services.msc
Найдите в списке службу Установщик Windows (Windows Installer), дважды кликните по ней. По умолчанию, параметры запуска службы должны выглядеть как на скриншотах ниже.
Обратите внимание, что в Windows 7 можно изменить тип запуска для установщика Windows — поставить «Автоматически», а в Windows 10 и 8.1 данное изменение заблокировано (решение — далее). Таким образом, если у вас Windows 7, попробуйте включить автоматический запуск службы установщика, перезагрузить компьютер и попробовать установить программу снова.
Важно: если у вас нет службы Установщик Windows или Windows Installer в services.msc, или если она есть, но вы не можете поменять тип запуска этой службы в Windows 10 и 8.1, решение для этих двух случаев описано в инструкции Не удалось получить доступ к службе установщика Windows Installer. Там же описаны пара дополнительных методов исправить рассматриваемую ошибку.
2. Исправление ошибки вручную
Еще один способ исправить ошибку, связанную с тем, что служба установщика Windows недоступна — заново зарегистрировать службу Windows Installer в системе.
Для этого запустите командную строку от имени администратора (в Windows 8 нажать Win + X и выбрать соответствующий пункт, в Windows 7 — найти командную строку в стандартных программах, кликнуть по ней правой кнопкой мыши, выбрать «Запуск от имени Администратора).
Если у вас 32-битная версия Windows, то введите по порядку следующие команды:
msiexec /unregister msiexec /register
Это перерегистрирует службу установщика в системе, после выполнения команд, перезагрузите компьютер.
Если у вас 64-битная версия Windows, то выполните по порядку следующие команды:
%windir%\system32\msiexec.exe /unregister %windir%\system32\msiexec.exe /regserver %windir%\syswow64\msiexec.exe /unregister %windir%\syswow64\msiexec.exe /regserver
И также перезагрузите компьютер. Ошибка должна исчезнуть. Если проблема сохраняется, попробуйте вручную запустить службу: откройте командную строку от имени администратора, а затем введите команду net start MSIServer и нажмите Enter.
3. Сброс параметров службы установщика Windows в реестре
Как правило, второго способа оказывается достаточно для исправления рассматриваемой ошибки установщика Windows. Однако, если проблему так и не удалось решить, рекомендую ознакомиться со способом сброса параметров службы в реестре, описанный на сайте Microsoft: http://support.microsoft.com/kb/2642495/ru
Обратите внимание, что способ с реестром может не подходить для Windows 8 (точной информации на этот счет дать, не могу.
Удачи!
