Download windows installer 7 maximum 64 bit. Why are programs from .msi files not installed? Windows installer doesn't work

Errors when installing applications from files with the .msi extension are one of the manifestations of problems with the service. Windows Installer(in the Russian version - Windows installer). Users of all versions of this OS, with the exception of the earliest ones, encounter a similar phenomenon. So far the problem with the installer is one of common reasons, according to which users decide to reinstall the system. Let's try to figure out how to avoid this. The reason that Windows Installer does not work may be the following:

  • viral infection, and removing the virus does not always solve the problem;
  • incorrect installation of Windows updates;
  • a malfunction of the security software when, instead of blocking one suspicious msi file, the installation service is blocked entirely;
  • changes in computer security policies;
  • damage system files or the registry for reasons not related to viruses (removal of installer components, unqualified editing of the registry, crooked software, malfunction hard drive and so on.).

Checking the integrity of the Windows Installer structure

The Windows Installer consists of the following components:
  • file C:\Windows\System32\Msiexec.exe - directly by the installer application itself;
  • file C:\Windows\System32\msi.dll - Windows Installer library;
  • Msiserver service, whose settings are stored in the registry key.
Before diagnosing, it is important to make sure that both of these files are present in the system, that the above section is in the registry and its parameters have normal values ​​(the values ​​can be viewed in the registry of a similar, working system). Also open the list of services (press Windows + R and enter the command services.msc in the "Open" line of the "Run" application). Find "Windows Installer" and make sure it starts. If the files are missing, copy them from another system of the same version or from the installation disk. If the registry key is missing or damaged, also transfer it from the working system. To do this, on a working computer, run the registry editor (C:\Windows\Regedt.exe) and find the above section. Right-click the context menu of the msiserver folder and click "Export". Save the file in .reg format and transfer it to the problem machine. Double-click this file and agree to add data to the registry. Restart your computer. If the Msiserver service still does not start, check that the RPC (Remote Procedure Call) service on which it depends is running. You can re-register the installer files and restart the service using a set of special commands on the command line. For convenience, you can create a batch file: paste a set of actions into Notepad and save it as a .bat extension. To launch a file, simply double-click on it. For the changes to take effect, click on the desktop and press F5.

Checking security settings and access rights

Windows Installer may not work because it is blocked by security software or operating system no necessary rights. First, let's look at the software. If you have an antivirus installed, temporarily disable it. Each product has its own methods of disabling, but most often this is done through the context menu of the antivirus icon in the system tray. Now let's take care of the rights. Open the context menu of Msiexec.exe and expand its properties. View the list of groups and users on the Security tab. Among them must be "System" and the "Trustedinstaller" service, and the latter must have full access to the file and be its owner. The system must have "read" and "read and execute" permissions. The Trustedinstaller service first appeared in Windows Vista, so in Windows XP full access must be granted to the system. Everything written below applies to versions released later than XP. To check who owns Msiexec.exe, click the "Advanced" button on the same tab. In the next window, expand the "Owner" tab. Set the owner to the Trustedinstaller service if something else is specified as the owner. If it is not in the "Change owner to" list, click the "Change" button, and then click "Other users and groups." Enter Trustedinstaller in the "Enter names..." field, click "Check names" and OK. Return to the previous window. On the "Effective Permissions" tab, assign the necessary rights to Trustedinstaller and the system. The msi.dll library should have exactly the same security settings. Now let's check if there are any restrictions for the "System" user to access the following:
  • system drive (usually drive C);
  • temporary folders (these are C:\Windows\Temp and C:\Users\Current_User\AppData\Temp);
  • folder C:\Config.Msi;
  • the folder where the msi file from which you are trying to install the program is located.
The system must be given full access to all these objects. This is done in the same way as we discussed above. After these operations, in most cases the problem with the installer is successfully resolved. If our advice did not help you, the cause of the failure lies in something else and specialists should deal with it.

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. At new installation or skype update Some users began to receive an error stating that they could not find or download the Microsoft installer 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 this skype installations, 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! windows error istaller appears if Skype is updated to 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, then the operating system must comply with 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 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 run the Skype installation.

Install windows 7 updates

Friends, this is 100% result. To be honest, I started with this decision, 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:

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 systems. 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 operating system installer. Windows systems;
  • 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, ordinary users PC it happens. 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 Windows versions 7 and Windows 8. The only difference between them is 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 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 a forum official support, 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.
