Let's start with why, in principle, this program is needed on a PC, and what functions it performs.

Typically those who were unable to access the installer service Windows Installer, fall into a stupor. In this article we will try to dispel once and for all the terrible myths about the criticality of this error, consider the main points and, just in case, other effective methods for solving the problem, some will be in the following parts.

Operating system service Windows Installer is an important link, a small subsystem of your main Windows system. It provides installation (installation) of most programs. Hence another name follows – installer. Without it, you will not be able to use programs that require installation to operate (that’s right, for some types of programs installation is not required, however, since you have already started reading this article, the case is different). Accordingly, it has the format .msi. There is nothing scary or incomprehensible in the letters of this format, just an abbreviation for the name of the earlier version Microsoft Installer.

The most common notification messages about malfunctions and errors are as follows:

• The Windows Installer service is unavailable;
• The Windows OS Installer service could not be accessed. This usually happens due to an incorrectly installed Windows operating system installer;
• Problems with the Windows Installer OS installer service: unable to access the service Windows Installer Windows 7/8/XP;
• The most common problem: Windows Installer It's just not installed.

Now let's move on to optimal and effective solutions to these problems.

Your first task will be to check whether the Windows installer service is running or not running on your OS, and in general, check the list of programs installed on the system for its presence. You may even have to download Windows Installer for Windows 7 x32, if you have such an OS, because it may especially often be absent from it.

In most cases, this is what happens to ordinary PC users. There can be quite a few reasons for this outcome: from viruses picked up on bad sites to incorrect or malfunctioning programs. However, the problem must be solved one way or another.

First, you need to check the list of services on your OS. To do this, press the key combination on your keyboard Windows (checkbox) + R(in this order), a window called “Run” should immediately appear on your PC screen. Next, to figure out why you can't access the service Windows Installer, in the empty field we print services.msc (there is no need to enter italics, I indicate it here for clarity). There is nothing complicated, everything will be something like this:

Next, click on the button called OK. A window will appear in front of you called "Services" . You will need to scroll through the list a little, strain your eyes and find a service called Windows Installer:

It may happen that you won’t find it - then you need to download it for free Windows Installer for Windows 7/8, etc. (you can do this at the end of the page). If you find it, great - double-click with the left mouse button and look at the following pictures. Here I give you examples for the OS versions of Windows 7 and Windows 8. The only difference between them is that on Windows 7 the user can switch the startup options between automatically and manually. On Windows 8, this can only be done forcibly.

If you own Windows 7, try selecting the automatic startup type option for the Windows installer. Reboot your iron friend after this procedure and try again to install the program you need.

In the event that your attempts to find something regarding Windows Installer are unsuccessful, you will need to install it. Hide-Info has versions for any Windows - for example, Windows Installer x64 for Windows 7 can be downloaded for free from the link below.

However, if you were unable to solve the problem, and you believe that your access is not limited by anyone, and old versions of the program were never detected, then you can turn to the “Reset service parameters in the registry” function. This information is available on the Microsoft website. For Windows 8, this method may not lead to the desired result, but, in any case, to implement it you will need to be thoroughly familiar with the official website. However, more often it’s enough to just download Windows Installer for Windows 7 32 bit and 64 bit, without making any changes to the registry body.

Below are links to other methods of dealing with this problem, download links Windows Installer , as well as the official support forum, although if you carefully read the other methods and do everything according to the instructions, then the official website will no longer be useful to you.

Using this installer, you can always install any program, as well as change some parameters. On our website you can download and install it completely free of charge.

Main reasons why this service may not work

So, if when you try to install a program, the message “Cannot access the Windows Installer service” pops up, then you just need to enable or download it.

In general, this installer comes with the operating system, but it happens that it may not work for the following reasons:

1. Access to the Windows 7 Installer service is prohibited because you are logged in as a guest.

How to start the installer service?

If the computer is yours, then you will just need to log in as an administrator (main user). If not yours, contact the administrator-manager or person responsible for computers.

1. The installer service has been disabled

If a message pops up with similar text, then this problem can be solved like this:

Download

Download this installer. Then all that remains is to launch and install it.

Windows is the operating system that powers most modern computers. Many not only games, but also applications are produced for it. But sometimes even the most reliable devices have problems. What to do if the program format is unknown to the computer, why does it not start? The problem can be solved simply by downloading and installing the Windows Installer service for Windows 7 x32.

About the purpose of the program

Thanks to this program, users will no longer have problems working with applications that have the msi extension. They can be removed, configured, and installed. The installer allows you to install and configure the necessary parameters at any time.

Difficulties with the service. And their reasons

You just need to download and enable the application if, when working with other programs, a message pops up stating that the service could not be accessed. Usually the installer comes bundled with the operating system itself. When is access to it closed? If the user did not log into his account, but saved the guest status.

Solving startup problems

Does the computer belong only to you? Then it is enough to use the rights of the main user or administrator and log in again. If the computer is someone else’s, you need to contact the person who is responsible for access to the system.

Sometimes a message appears indicating that the service has been disabled altogether. There is nothing complicated in such a situation either.

Problems arise due to the fact that the version of the program is outdated, or this tool is missing altogether. Then you just need to find the service on the Internet and install it. Starting from version 7 of Windows, the program is compatible with all the latest operating systems.

The operating system consists of a huge number of programs and services, each of which performs its own functions. For example, to install new programs on your computer, you use Windows Installer, an installer service for Windows 7. It is responsible for unpacking files and entering data into the system registry. Some users, when trying to install applications, encounter the error “Could not access the service,” as a result of which the installation of the program becomes impossible. This article presents ways to solve the problem.

A similar error may occur if the corresponding service has been disabled, system files or registry entries are damaged. Below are ways to solve such problems.

"scan now" command

If, as a result of viruses or system failures, any important system files responsible for Installer have been damaged, you can use a special command for the console to identify and fix errors. You need to do the following:

After that, try calling Installer again by starting the installation of some application. If the problem is not resolved, proceed to the next step in the guide.

Service Manager

It is possible that Installer is not working because the service that is responsible for it is disabled. Try opening the manager and turning it on. If you don't know how to do this, follow the instructions:

If the required item is not in the list provided, call the command line. How to do this is described above in the previous section of the manual. In the console you need to enter the command “net start MSIServer” and press Enter. If no problems occur, you will see the message “Windows Installer started successfully.”

Registry export

You can also find a copy of someone else's registry key online and import it into your computer. The directory you need is called "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\msiserver".

This is a small specialized utility from Microsoft that is needed to install applications from .msi packages, which can be found very often these days. Why are they so widespread? It's simple, when installing, Windows Installer will remember all the changes made to the system, so after you decide to uninstall a program installed through this package, your application will completely roll back all the changes made to the system, that is, a completely correct uninstallation will occur. Both software developers and we, users, like this, because no one wants to clog the system with unnecessary garbage. If you have problems with this package, I recommend downloading Windows Installer for free from our website, I think all problems will be solved.

Please note that when installing Windows, you will already have this package in your system, but there are various reasons why you need to reinstall it or you simply want to update the version, but Windows itself did not offer you to do this, this is where Microsoft Windows will help Installer. I myself had a problem with this package and I could not install a large number of programs on the system due to the fact that they were packaged in .msi. To work, you just need to run the package downloaded from our website for your OS, then follow the instructions, everything is very simple and does not require any settings, as a result you will receive an updated version of the program.

Developers really like Windows Installer because it gives them additional options, for example, you can insert a new dialog into your installer, which will be responsible for choosing the installation path, you can add additional installation parameters, you can add a license agreement, information about yourself, and so on.

So, dear friends, if you need to download Microsoft Windows Installer for Windows XP or Vista, you can do it from our website just below in the news, thank you all for your attention and good luck!
