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, Windows Installer is used - the 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 can occur if the corresponding service has been disabled, system files or registry entries are damaged. The following are ways to resolve such problems.
"scan now" command
If any important system files responsible for the Installer have been damaged as a result of viruses or system failures, you can use a special command for the console to detect and fix errors. You need to do the following:
After that, try calling the Installer again by starting the installation of some application. If the problem is not resolved, go to the next step in the guide.
Service Manager
Perhaps the Installer is not working due to a disabled service that is responsible for it. Try opening the manager and enable it. If you do not know how to do this, follow the instructions:
If the required element is not in the presented list, 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 there are no problems, you will see the message "Windows Installer ran successfully."
Registry export
You can also find a copy of someone else's registry key online and import it to 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 are very common these days. Why are they so widespread? It's simple, when installing, Windows Installer will remember all changes made to the system, so after you decide to remove the program installed through this package, your application will completely roll back all changes made to the system, that is, a completely correct uninstallation will occur. Both software developers and us users like it, because no one wants to litter the system with unnecessary garbage.

In this article, we will try to dispel the terrible myths about the criticality of this error once and for all, 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 the other name - the installer. You will not be able to use programs without it that require installation for their work (that's right, for some types of programs, installation is not required, however, since you are already reading this article, the case is different here). It has the format .msi. There is nothing terrible and incomprehensible in the letters of this format, just an abbreviation for the name of the early version Microsoft Installer.
The most common fault and error messages are as follows:
- The Windows Installer service is unavailable;
- The Windows Installer service could not be accessed. This usually happens due to an incorrectly installed installer for the Windows operating system;
- Windows Installer Service Issues: Failed to access the service Windows Installer Windows 7/8/XP;
- The most common problem: Windows Installer just not installed.
Now let's move on to the 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 indeed, to check the list of programs installed on the system for its presence. You may even need to download Windows Installer for Windows 7 x32, if you have such an OS, because on it, he especially often may be absent.
In most cases, this 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 incorrectly working programs. However, one way or another, the problem must be solved.
First you need to check the list of services of your OS. To do this, press the key combination on the keyboard Windows (checkbox) + R(in that order), a window called "Run" should immediately appear on your PC screen. Next, to understand why the service cannot be accessed Windows Installer, in the empty field we type services.msc (Italics do not need to be entered, I indicate it here for clarity). There is nothing complicated, everything will be something like this:

It may be that you will not 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 - click the left mouse button twice, look at the following pictures. Here I give you examples for OS versions of Windows 7 and Windows 8. The difference between them is only that on Windows 7 the user can switch startup options between automatically and manually. On Windows 8, this can only be done forcibly.
If you own Windows 7, try choosing the automatic startup type option of 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 failed, 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 still failed to solve the problem, and you believe that your access is not limited to anyone, and the old versions of the program have not been detected, then you can refer to the "Reset service settings 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 familiarize yourself with the official site. However, more often it is enough just to download Windows Installer for Windows 7 32 bit and 64 bit without making any changes in the body of the registry.
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 other methods and do everything according to the instructions, then the official site will no longer be useful to you.

The error may appear regardless of your OS version.
Reasons for the error
You can run an OS scan using the Sfc /scannow command. You need to enter it in the command line window.
You can also start the command line in two more ways:

- Start -> Run and enter the name of the program cmd.exe
In a few minutes, you will be provided with detailed information about OS disks, corrupted files, problems with services and other system programs.
The command line will not only find corrupted and damaged files, but also replace them with workable ones.
After scanning, close the command prompt and restart your personal computer or laptop. Try to run the installation process of any executable file.
Microsoft also offers users an automatic utility that can solve the problem of the installer.
Go to the web address of the company's official website https://support.microsoft.com/ru-ru/mats/program_install_and_uninstall
In the window that opens, click on the "Run now" button. The utility will restore the correct configuration of the installer.
It is worth noting that the utility does not work with the eighth version of the operating system.
Configuring Installer Access to msi Files
Installation failure may be caused by the installer not having access to msi files. The user can solve this problem himself.
Follow the instructions below:
- Find your installation file and right-click on it;
- Select the properties window;
- Go to the security settings tab;
- In the groups or users text box, check if there is a user named "system". If it is not there, you must add the user manually;
- To add a new user, click on the Edit button and then on the Add button;
- In the text field for the names of the selected object, write the word "system" (without quotes). If you are using an English version of the operating system, enter the word System;
- The entered word should instantly become underlined, as shown in the figure below;
- Check the box next to the full access field and now click on the OK button;
The installer will now be able to access the executable. The installation should complete without problems.
