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.

Windows Installer Error - Troubleshooting

A fairly common problem among users of the Windows operating system of any version is the 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 solutions to them, and also make a video on the current issue.

Files with the .msi extension are regular installation packages (distributions) from which the program is installed. Unlike the usual “setup.exe”, the system uses the Windows Installer service (msiexec.exe process) to launch the msi file. In simple terms, Windows Installer unzips and runs files from the distribution. When Windows Installer does not work, various errors appear.

In general, this really infuriates me, because... After a stupid error message, it’s completely unclear what to do next. Microsoft specifically designed the Windows Installer to enhance the ability to install programs (mainly for system administrators), but did not take proper care to ensure that the service would run smoothly or even adequately report problems. Now we have to sort it out :)

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 tinker with the installer service, and in the second, solve a problem with a specific file. Let's consider both options, but first the second one.

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, you just need to add the necessary rights and everything will work. Just yesterday I was faced with the fact that the downloaded distribution kit.msi did not want to be installed, 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, aren't you stupid? Naturally, the “Retry” button does not help, and canceling stops the entire installation. The message also does not carry any special meaning, because the file definitely exists and I have access to it, otherwise I simply wouldn’t be able to run it and receive this message, and for some reason it’s in English :)

And the mistake 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. Watch a video on solving problems with access rights:

In Windows XP, the Security tab will not appear if simple file sharing is enabled. 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 stripped-down versions of Windows 7/10 and XP, there is no “Security” tab at all. To see it, you need to log in as an administrator.

Registry and service settings

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

To do this, download the archive and run two reg files from there, corresponding to your version of Windows. Agree to import settings.

Important! It is advisable before the last action! If the method does not help or gets worse, you can recover to your previous state.

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

If this does not help, then re-register the components:

Press "Win + R" and enter " cmd". Then in the black window enter the following commands in sequence:
MSIExec /unregister
MSIExec /regserver
The answer should be empty, no errors. If the problem is not solved, enter another command
regsvr32 msi.dll
Close the black window

If it says that you do not have enough rights, then you need to run .

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

The last option is to download the Kerish Doctor program, it has a function for fixing the installer service and many other common Windows problems.

Also, many programs use the .NET Framework, so it would be a good idea to install the latest version of this package. And, finally, one more piece of advice: if in the path to the distribution file there is at least one folder with a space at the beginning of the name, then remove the space. This simple trick will solve your problem :)

Summing up

Errors with the Windows installer are very unpleasant, there are a lot of them and it’s not immediately clear where to look. One thing is clear - the system has failed and needs to be restored to working condition. Sometimes nothing helps and you have to. However, do not rush to do this, try asking for help on this forum. Describe your problem exactly, tell us what you have already done, what messages you have received, and perhaps they will help you! After all, the world is not without good people :)

If programs from .msi files do not start, this is a direct indication of a problem with the Windows Installer service. Any Windows 7 OS user may encounter a similar phenomenon. Therefore, if Windows Installer does not work for you, it is worth familiarizing yourself with some recommendations.

Reasons for Windows Installer failures

The reasons why Windows Installer does not work may be due to the following factors:

Virus infection of system files. However, cleaning the OS does not always solve the problem.
Incorrect installation of updates.
Incorrect editing of the registry, removal of installer components.
Blocking the .msi file by the antivirus
Changing PC security policy.

All of these factors can affect the operation of the Windows Installer service.

Checking the integrity and functionality of files

Windows Installer consists of the following components:

The file msiexec.exe, which is located on the “C” drive in the “Windows” and “System32” folder.
The file is msi.dll, which is nothing more than an installer library.
The Msiserver service, whose parameters are located in the registry editor section at the addresses "HKEY_LOCAL_MACHINE", "SYSTEM", "CurrentControlSet", "services" and "msiserver".

First, go to the registry editor and look at the value of the msiserver service. Click “Win + R” and enter “regedit”.

We make sure there are no unnecessary values. The correct list is shown in the photo.

If there is no partition or some files are missing, you can copy the elements on the working system and right-click and select “Export”.

Select a location to save the files and enter a name similar to the original. Click “Save”.

Move the copied section or files to your PC.

Find “Windows Installer” and check if the service is running.

If necessary, double-click the file and click “Run”.

Checking access rights

Launch the registry editor, go to the address “HKEY_LOCAL_MACHINE”, “Software”, “Microsoft”, “Windows”, “CurrentVersion”, “Installer”. Right-click on the section name and select “Resolution...”.

In the “Groups and Users” section, click “System”. Next, we make sure that the user has full access to the service.
