Windows 7 installer is not installed what to do. Unable to access Windows Installer service - Windows error

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


Usually those who were unable to access the installer service Windows Installer fall into a stupor. 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, others effective methods solutions to the problem, some will be in the next parts.


Service operating system Windows Installer is an important link, a small subsystem of your main Windows systems... It provides installation (installation) of most programs. Hence a different name follows - the installer. You will not be able to use programs that require installation for their work without it (just like that, for some types of programs, installation is not required, however, since you are reading this article, then the case is different). Has, accordingly, the format .msi... There is nothing terrible and incomprehensible in the letters of this format, just an abbreviation for the name early version MicroSoft Installer.


The most common error and error messages are as follows:

  • The Windows Installer service is not available;
  • Windows OS Installer Service could not be accessed. This is usually due to an incorrectly installed Windows operating system installer;
  • Problems with the Windows Installer service installer: could not 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 have to download at all Windows Installer for Windows 7 x32, if you have such an OS. on it he may be absent especially often.


In most cases, this is the case for 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, the problem, one way or another, must be solved.


First, you need to check the list of services for your OS. Press the key combination on the keyboard for this Windows (checkbox) + R(in this order), a window called "Run" should immediately appear on the screen of your PC. Next, to understand why the service cannot be accessed Windows Installer, in an empty field we type services.msc (It is not necessary to enter it in italics, here I indicate it 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" ... In the list, you will need to flip through a little, strain your eyes and find a service called Windows Installer:



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 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 automatic and manual. On Windows 8, this can only be done by force.




If you own Windows 7, try to select 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 with regards to Windows Installer are not successful, you will need to install it. Hide-Info has its 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 did not manage to solve the problem, and you believe that your access is not restricted by anyone, and the old versions of the program have not been found, then you can refer to the function “Reset service parameters in the registry”. This information is available on the site Microsoft... For Windows 8, this method may not result in desired result, but in any case, to implement it, you will need to familiarize yourself well with the official site. However, more often it is just enough to 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 an official support forum, although if you carefully familiarize yourself with other methods and do everything according to the instructions, then the official site will no longer be useful to you.


A fairly common problem among users of the Windows operating system of any version is an msi error when installing programs from a file with the .msi extension. In this article, I will describe common problems with the Windows 7/10 / XP installer and options for solving them, as well as make a video on the current issue.

Files with the .msi extension are the usual installation packages (distributions) from which the program is installed. Unlike the usual "setup.exe", to run msi file the system uses the Windows Installer service (msiexec.exe process). Speaking in simple words, Windows Installer will unzip and run the files from the distribution. When Windows Installer doesn't work, various errors appear.

In general, it pisses me off terribly, tk. after a stupid error message, it is completely unclear what to do next. Microsoft specifically designed the Windows Installer to enhance the installation of programs (mainly for system administrators), but did not properly take care of the smooth operation of this service or even adequate reporting of problems. And now we have to rake it 🙂

Problems may be with the operation of the service itself or may arise during the installation of programs, when everything is configured, in principle, correctly. In the first case, you need to pick the installer service, and in the second, solve the problem with a specific file. Let's consider both options, but first the second.

Msi file errors

Very often errors appear due to insufficient system rights to files or folders. This is not to say that Windows Installer does not work, in this case it is enough to simply add necessary rights and everything will work. Just yesterday I was faced with the fact that the downloaded .msi distribution did not want to be installed, while the installation wizard starts successfully, the parameters are selected, but then the system thinks for a few seconds and gives an error:

"Error reading from file" filename "verify that the file exists and that you can access it" (Error 1305). Translated "Error reading from file ... check if the file exists and if you have access to it." Well, isn't he stupid? Naturally, the "Retry" button does not help, and canceling terminates the entire installation. The message also does not carry a special semantic load, since the file definitely exists and I have access to it, otherwise I would simply not be able to run it and receive this message, besides, for some reason, in English 🙂

And the error is that it is not I who should have access to the file, but the Windows installer, or rather the System itself. The solution is very simple:

Now the installer error will not appear! You can add access to the entire folder from which you usually install programs, for example, to the Downloads folder, like mine. We watch a video on solving problems with access rights:

In Windows XP, the Security tab will not appear if the simple general access to files. To turn it off, you need to go to "Start -> Control Panel -> Folder Options -> View" and turn off the "Use simple file sharing" option. In the stripped-down versions of Windows 7/10 and XP, the Security tab does not exist at all. To see it, you need to boot Windows into safe mode and log into it as an administrator.

More ways to solve the problem


The described method will help with different messages, with different numbers. For example, you may see errors like these in msi files:

  • Error 1723
  • Internal Error 2203
  • System error 2147287035
  • Error "This installation package cannot be opened"
  • Error 1603: A fatal error occurred during installation

In all these cases, setting the rights to the file and / or to some system folders... Check if the "system" has access to the temporary files folder (you may receive the error "The system cannot open the specified device or file"). For this:

After pressing "Enter" the path will be converted to "normal" and you will move to the real temporary folder. The rights to it should be checked. I also recommend that you clear the temporary folders from everything that has accumulated there, or even better, delete them and create new ones with the same names. If you can't delete a folder, read it, but it's not necessary.

If windows service Installer still does not want to work, then check the rights to the folder "C: \ Config.Msi", here the "system" must also have full access. In this case, you might have seen the "Error 1310" error. Just in case, make sure that you also have all rights to the folder WHERE you install the software.

Registry settings and services

The next way to fix the error is to restore the operating parameters in the registry. Windows Installer Installer.

To do this, download the archive and run two reg-files from there, according to your Windows versions... Agree to import settings.

Important! It is advisable before the last action! If the method doesn't work or gets worse, you can recover to your previous state.

On Windows XP or Windows Server 2000 install latest version installer 4.5.

If it doesn't help, then do another re-registration of the components:

  1. Press "Win + R" and enter " cmd ". Then, in a black window, enter the following commands in sequence:
    MSIExec / unregister
    MSIExec / regserver
  2. In response, there should be emptiness, no mistakes. If the problem is not resolved, enter another command
    regsvr32 msi.dll
  3. Close the black window

If he writes that there are not enough rights, then you need to run.

If the commands were executed, but did not help, then run msi_error.bat from the archive, check the result.

The last option is to download the Kerish Doctor program, there is a function for fixing the work of the installer service and many others frequent problems Windows.

Also, many programs use the .NET Framework, so it won't be superfluous to install the latest version of this package. And, finally, one more piece of advice: if the path to the distribution file contains at least one folder with a space at the beginning of the name, then remove the space. Such a simple trick will solve your problem 🙂

Summarizing

Errors with the Windows Installer are very unpleasant, there are a lot of them and it is not immediately clear where to dig. One thing is clear - the system has failed and you need to restore it to a working state. Sometimes nothing helps and you have to. However, take your time to do this, try asking for help on this forum. Describe your problem exactly, tell us what you have already done, what messages you received, and, perhaps, they will help you! After all, the world is not without kind people 🙂


Sometimes it happens that when you install a program, you get a system Windows message about the inability to access this service:

Unable to access the Windows Installer service. The Windows Installer may not be installed. Please contact support for assistance.

First, let's define what Windows Installer is. It is a system service that is responsible for installing, modifying, and removing programs that have the .msi extension. There are several reasons for this problem. Let's consider them below.

First reason, on which this error may occur lies in the restriction of your user rights to this computer... In this case, you should try to install the program with administrator rights (this is done by right-clicking on the app icon.

Ozhenie).

The second reason may be hiding in the system services settings, so check them. It is done like this: "Start" - "Control Panel" - "System and Security" - "Administrative Tools" - "Services".

In the "Services (local)" window that opens, at the very bottom of the list, find the "Windows Installer" section and double-click on this item with the left mouse button.

The window for configuring the installer service will open, we need the "General" tab. The line "Startup type" should be set to "Manual". And make sure that the quality executable file appears:

C: \ WINDOWS \ system32 \ msiexec.exe / V

Instead of C there can be, for example, the letter D - these are the letters of the local drives.

Now go to the "Dependencies" tab. In a large window This service depends on the following components should be written " Remote call procedures (RPC) "as in the image below:

Third reason may be hidden in the program's association for files with the .msi extension. Open the menu "Start" - "Control Panel" - "Programs" - "Programs by default" - "Set mapping". If your mapping is not set, or Windows Installer is not listed there, you need to fix it, as shown in the picture below:

The installer program is called msiexec.exe and is located in the System32 directory (it's easier to find it by searching, as shown above).

During the normal installation of the program, some users are "lucky" to encounter a system message about problems with the Windows installer: it seems like access to it is impossible, such a service is not connected, or, in principle, such software missing from the system. Little pleasant, right? But is there a chance to get rid of this "gift" without reinstalling Windows? This is not an easy question. However, if desired, reanimate windows installer v Windows system 7, you can use this step-by-step instruction.

Step # 1: Checking for Service Availability

In the event that the Windows installer for some reason does not work, before complaining about your plight, you need to clarify whether there is, in principle, such a program on the computer. How to do it? It is enough to select on the keyboard and R further, in the window that appears, drive in the value of msiexec and and click OK:

As a result, if Windows Installer is installed on the computer, something like the following system notification window will appear:

If the miracle did not happen (for example, an error message or the absence of such a program in Windows 7 appeared), you can immediately skip to step number 5, since a simple reconfiguration is not enough. It happens rarely, but still. If everything is fine, the window appeared as it should, move on and try to reanimate the Windows installer on our own.

Step # 2: Attempt to start the service

Having established that Windows Installer is on the computer, you need to clarify whether this service is connected in the system or not. How to do it? First, choose one of the following options:


One way or another, the result of such actions will be the appearance on the screen of the "Services" window. In it we find the item "Windows Installer", click on it with the mouse and check the data indicated opposite it in the "Status" column. What will indicate its performance? The value "Works". If the column is empty, then most likely the service is not running. In this case, in the upper left corner we find the corresponding button ("Run") and execute Windows launch Installer:

In the event that the "Status" column indicates that the installer is working, although this does not correspond to reality at all, you can try to restart this service by clicking the corresponding item in the upper left corner. After that, all that remains is to restart the computer and test the performance of the Windows Installer. If, after such settings, the program returns to normal, we can congratulate ourselves, this is where the "torment" is over. Otherwise, you will have to "step" further.

Step # 3: Re-register the service via the command line

You can return the Windows 7 installer to normal operation by re-registering such a service in the system. How do we act?

We go to the "Start" menu, set the cmd value to the search and press Enter. Next, we drive the msiexec / unregister parameter into the console that appears, click Enter, and then after the command line response, enter the msiexec / register value into it and press Enter again:

We repeat the input of commands if we are dealing with 64-bit Windows 7, and then restart the computer. In principle, this is often where all the difficulties with Windows Installer end. However, if the working atmosphere did not return to the Windows installer after that, before reinstalling it, you can try to reanimate it through the registry editor. But what if?

Step # 4: Debug via Registry Editor

You can try to resurrect Windows Installer through the registry editor in this way:

and delete all available parameters in them:

If there is no data in the destination folders, click right click mouse on the Installer folder, and then click on the "Permissions" item in the list that appears. Next, in the window that opens, click System, mark the "Full Control" parameter and click OK:

After that, we restart the computer and check the health of the service. If it didn't work this time, go to step 5 and reinstall it in Windows 7.

Step # 5: Reinstall the service

For reinstalling windows Installer, in principle, does not require any special tweaks. It is enough to copy the msiserver folder on the computer running the service (branch in the register editor - HKEY_LOCAL_MACHINE - SYSTEM –CurrentControlSet - services), transfer it to the appropriate folder on the PC with Windows 7, reboot the system and restart the service in the way indicated in step 2. That's it!

It is rare to deal with applications distributed in the form of MSI installers, but for some reason they are the ones that cause the most problems for users. The most common of these is the "Unable to access the Windows Installer service" error, which you can encounter on any version of Windows. In most cases, the error is associated with incorrect work the corresponding service - Windows Installer or msiserver. Most often, it turns out to be disabled when checked. You can make sure that everything is in order with the service as follows.

Open the services.msc command in the service management snap-in and look for Windows Installer in the list.

By default, this service is in an inactive state and the startup type is set to Manual.

In theory, when the executable MSI file is launched, it should be automatically activated, but this will not happen if, for some reason, the startup type is set to Disabled. You need to change the settings by selecting the "Manual" option in the drop-down list, but most likely the settings will be unavailable, which is typical for Windows 10. You will have to work around it.

Open the HKEY_LOCAL_MACHINE / System / CurrentControlSet / Services / msiserver key in the registry editor and change the value of the Start parameter from 4 to 3, and then reboot.

The launch type will change to Manual, and the launch button will become active. To set the startup type to Automatic, replace the Start value with 2. Since the msiserver service is dependent, we recommend that you also check the status of the RPC service. It must be running and the startup type must be "Automatic".

It may be that the Windows Installer service will not be listed at all. The most likely reason for this is corruption of the data in the registry responsible for it. In this case, try to restore it by merging the Windows_Installer.reg file available at https://cloud.mail.ru/public/2eVp/mWmQUP8FG. After applying the tweak, you will need to restart your computer. You can also update the operating system to the latest current build, if this option is acceptable to you.

It's also a good idea to check your Windows Installer policy settings. Call the editor with the gpedit.msc command local policies and go to the chain Computer Configuration - Administrative Templates - Windows components- Windows Installer. All policies must have a status of Not Configured.

Check the settings in the User Configuration section in the same way.

Finally, you can restore the normal operation of the Windows Installer service by manually re-registering it. To do this, open as administrator command line and sequentially execute the commands specified in this text file- https://cloud.mail.ru/public/9bBp/bYNiRVB82. After re-registering the service, the computer should be restarted, and then start the installer service with the net start MSIServer command, if for some reason it does not start itself.
