Windows Installer error - How to solve the problem. Why are programs from .msi files not installed? Windows installer does not work How to update the installer on Windows 7 professional

Windows installer error is one of the most common pop-up problems encountered by users of the Windows operating system.

The error may appear regardless of your OS version.

Reasons for the error

You can scan the OS using the Sfc /scannow command. You need to enter it into the command line window.

You can also launch the command line in two other ways:

• Start -> All Programs -> Accessories -> Command Prompt.
• Start -> Run and enter the program name 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 corrupted files, but also replace them with functional ones.

After scanning, close the command prompt and restart your personal computer or laptop. Try running the installation process of any executable file.

Microsoft also offers users an automatic utility that can solve the problem with 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

The installation problem may be caused by the installer not having access to msi files. The user can resolve this problem independently.

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 to see if there is a user named "system". If it is not there, you need to 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 the 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 Full access and now click on the OK button;

The installer will now be able to access the executable file. The installation should complete without problems.

Please note that in some cases antivirus software may block access to the installation file.

To solve this problem, you need to log into the operating system under an administrator account, turn off the antivirus and enable compatibility with other OS versions in the antivirus properties settings, as shown in the figure below.

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".

Good day ladies and gentlemen! Are you trying to install the most popular communication program? And then during installation a bug came out! I won’t be mistaken if you are looking for how to deal with an error when installing Skype. The most interesting thing is that until recently, when installing Skype on a clean Windows OS, no such problems were observed. When installing or updating Skype again, some users began to receive an error stating that the Microsoft installer could not be found or loaded when installing Skype.

Perhaps Skype adds new requirements for Windows 7. And this is not surprising. The era of Windows 7 is gradually fading away. But don’t despair, there is a solution! The error can be solved in several ways, the only thing you need to figure out is which option is right for you.

Just like you, I encountered this problem, reinstalled Windows 7, installed the necessary set of programs for comfortable work on the computer. It came to installing Skype, as expected, downloaded and launched the installation, nothing foreshadowed trouble. And here you have a piece of luck, you couldn’t find the microsoft installer or launch it! We've arrived.

I started to figure it out, read the forums. I found an interesting thing. The Skype support service recommends an alternative solution, in other words a temporary one, for those who do not want to bother and look for methods to resolve the error. You need to download and install the MSI installer:

But this is not a way out of the situation, but just a temporary cure that, as usual, will stop working at the most inopportune moment. As is usually the case.

Why does Microsoft installer error occur during installation?

Let's figure out what it is and what it is eaten with! The windows istaller error appears when updating Skype to a new version or during a new installation. As always, everything is done for the benefit of the user. Improvements in terms of security, usefulness and all that. While the matter is closely related to the security of the program, the operating system must, accordingly, meet security requirements. The bar for Win7 OS has been raised from skype. This is not observed for Windows 8, 8.1 and Win10.

Simply put, you need to update outdated Win7 OS components. But which ones, you ask, and I also asked this question)) I started with the update package for the operating system itself. More on this below.

By the way, there is no point in installing the Windows installer separately. Verified.

If you want to try installing the windows installer separately, you can download the microsoft website from the link below and try it. Only if you succeed, describe your situation and share with people who also encountered the error. Personally, a separate installation did not help me.

I solved the problem by installing the update package. Read below how to do this.

Install or update Internet Explorer 11

The correct method when an error occurs: the microsoft installer could not be found or downloaded; you need to install/reinstall IE11 on your PC. If you believe the official requirements of skype for windows 7 SP1, Internet Explore 11 must be installed for normal operation. Even if IE11 is installed, you should download and run the installation again. Which in turn will install the necessary updates for using Skype.

You need to start by checking the version of IE installed on your computer. To do this, go to Internet Explorer, click on the gear and select an item in the menu About the program. As a result, you will see a window with the IE version.

If you have a version lower than 11, then you need to use Item Reference and select it About the program. What to do if there is no gear or Help, just press the Alt key in the browser. And you will see a menu.

If you have Explorer below version 11, updating is mandatory, it’s not even discussed! In cases where the version corresponds to the latest version 11, you need to download the distribution and reinstall.

Select the operating system you need and download from the link below:

Install, restart your computer and try to launch the Skype installation.

Install windows 7 updates

Friends, this is 100% result. To be honest, I started with this solution because... After installation, the operating system turns out to be “bare”, no updates, no drivers, nothing, unless you have a build. In which some updates may be included in the installation.

The advantages of this method are installing new things, and Windows itself will not struggle to download gradually and update itself and solve the problem with Skype. Let's kill two birds with one stone!

The package you need install KB2533623 for windows 7, if you don't update your OS. Or maybe the update is completely turned off, or you don’t confirm the system update.

Why are such requirements made, so that your computer has all the important fixes from Mexosoft. Or maybe Skype together with Bill Gates)). So that everyone switches to modern OS. As I said earlier, the time of Windows 7 is passing, and official support is no longer provided. Who remembers how it was with windows xp.

After downloading, install the updates, the system will reboot several times and you can try installing Skype.

As a result, we get all the critical system fixes installed, plus Skype itself is installed, without problems, which is exactly what we need.

Download and install the full Skype installer

You can try another method in cases where the error message is skype could not find the microsoft installer. The point is to download the full Skype distribution, or an offline installer and then install it.

You must first install compatibility mode for Windows XP SP3. Here is the link on the official website for downloading:

Click right click by distribution, further Properties. Select a tab Compatibility, put a tick Run the program in compatibility mode for Windows XP (Service Pack 3), further OK.

Start the installation. The option is working, verified.

Let's summarize what has been done. We have learned what to do when an error occurs - Could not find microsoft installer when installing skype, three proven solutions that you can easily do
b, plus it won't take much time. We sorted out the problem ourselves, without resorting to paid services from an IT specialist, and personal satisfaction, which is no less important.

Microsoft Windows Installer is a freely available system component that provides software developers with the ability to more easily develop installation programs. This component provides the basis for installing and uninstalling programs in a Microsoft Windows environment.

One of the most important features of Windows Installer is the Multiple Package Transaction technology. Thanks to it, if for some reason the installation of the application was interrupted or completed unsuccessfully, all changes made by the installation will be canceled. In addition, when installing multiple components, there is no need to restart the computer each time. Windows Installer will take care of everything. In addition to installation, this tool is well suited for applying patches. This replaces only the necessary files and makes only the necessary changes. If a patch is removed, all changes made by other patches will not be affected. There is also a feature to embed your own user interface into the installer.
