Greetings, dear readers. In general, after the next one on the laptop, I, as usual, and the software necessary for the user.
Everything seemed to be fine, I installed it without any problems required applications, until it was time for Skype. As soon as I tried to run the installation of this particular program, an error message appeared on the screen with the error “Could not find or download Microsoft Installer».
Also, below it was said that you should download and install this update and restart Skype again. But there was no detailed information about what Microsoft Installer is and what it is.
At first, of course, I thought it could be Windows Installer, but after I downloaded it and tried to install it on my computer, I realized that my opinion was wrong.
Then I tried installing an earlier version of Skype ( by the way I did it) and update it directly from the software environment, but as a result I again encountered the same Microsoft problem Installer.
How, after all, to install Skype and bypass the error with installing Microsoft Installer
After several attempts to solve this problem myself, I ran automatic update systems to install all missing components.
As a result, after the update was completed, Skype installed and launched without problems.
As it turned out, I later found out that for a full-fledged Skype works, required Internet Explorer 11.
The only thing that surprised me was that the Windows 7 distribution from which the system was installed had been used before, and all programs installed perfectly and were updated without problems, and in Skype such errors as “Could not find or load Microsoft Installer” never appeared.
Well, okay, in general, in order to get rid of the problem with Microsoft Installer, when installing Skype, you just need to update IE to version 11.
How to download and update Internet Explorer 11
You have two options:
- Run a full scan and installation of system updates;
- Download installation file IE 11 from the site and install it manually;
Option #1
You can launch a full system update from the “Update Center”, to do this you need to go to
Just in case, let me remind you that in the “top ten” you can get to the control panel by right-clicking on the “Start” menu icon and selecting the appropriate item.
Option No. 2
You can download IE 11 directly from the Microsoft website using this link:
Save the installation file to your computer and then open it.
The update will start current version IExlorer up to 11.
After the update installation is complete, try launching Skype. If you get to at least the first step of the Skype installation, then everything is ok and there is an error Microsoft installations Installer won't bother you.

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, or the system files or registry entries. 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.
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 system Windows. 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 incorrect installed installer operating room Windows systems;
- Problems with the OS Installer service Windows Installer: Failed to access 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 website Microsoft. 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.
Windows Installer ( Windows installer) is a computer program necessary for installing, configuring and uninstalling applications prepared for distribution in the Microsoft installer (files with the .msi extension). Is a component Microsoft Windows, starting with Microsoft Windows 2000, but can also be installed on earlier Microsoft versions Windows.
By using installers created specifically for Windows Installer, users get a simpler and quick installation programs, an on-demand installation function, a program self-healing function, powerful rollback capabilities and many other useful features that greatly facilitate the process of installing, configuring and uninstalling programs.
Logical package structure
- The installation package describes the installation of one product and has its own GUID.
The product consists of components (also having their own GUIDs), grouped into capabilities (features).
- Component is a minimal indivisible installation unit, which is a group of files, registry values, created folders and other elements, united by a common name (component name) and either installed together or not installed.
Components are hidden from the end user. Each component has a key path - for example, the name of its main file - which determines the presence of this component on the user's computer.
- A feature (feature; in the Russian version of Microsoft Windows this word is translated as “component,” which causes confusion) is a hierarchical group of components and/or other capabilities.
When a dialog for selecting installed parts of the program is displayed during installation, the user controls the choice of features. Selecting an installation option entails installing all the components that are included in it.
Physical package structure
- The .msi file is an OLE compound document (OLE compound document - stored in the same container format Microsoft documents Word, Microsoft Excel etc.), which contains a small relational database - a set of several dozen interconnected tables containing various information about the product and installation process.
In this case, all string data in the database is stored together in a separate document stream, and there are links to them in the database tables; This way duplication of rows is avoided, which significantly reduces the size of the database.
- In addition to the base, the structure of the .msi file provides for placing there user scripts and auxiliary DLLs, if required for installation, as well as the installed files themselves, packed in the .cab format.
Files can be placed separately from the package, in packed or unpacked form (while maintaining the directory structure).
Note
Latest versions operating systems Microsoft Windows (starting with Microsoft Windows XP Service Pack 3) already have a built-in Windows Installer, and usually do not need to install it.
