It gives a windows installer error. Why are programs from .msi files not installed? Windows installer doesn't work
Some programs and drivers in Windows should only be installed with administrator rights. In the case of EXE files, the option to install as administrator is present in the context menu, which is called up by right-clicking on the file. There is no such option for MSI packages, but you can add it through the registry editor.
Instructions
Open the Run dialog via start menu or by pressing the Win+R key combination. In the window that opens, write regedit and press Enter. The Registry Editor will launch. Depending on your User Account Control settings, you may be asked to confirm that you want to launch the editor.
Go to the HKEY_CLASSES_ROOT\Msi.Package\shell branch. Click right click mouse on “shell” and in the menu that opens, select the option to create a new partition.
A subsection will be added to the “shell” section. Rename it "runas" (no quotes needed).
In the window on the right, double-click on the “Default” key or once with the right mouse button and select “Change...” In the empty value field, enter “Run as Administrator”. Confirm the changes by pressing the OK button.
Now right-click on “runas” and select the create partition option again. Create a subkey named "command" (without the quotes).
Edit the "Default" key by entering the command "msiexec /i "%1"" in the value field (without the herringbone quotes, but with quotes for %1). Click OK.
Errors when installing applications from files with the .msi extension are one of the manifestations of problems with the Windows Installer service (in Russian version- Windows installer). WITH similar phenomenon Users of all versions of this OS encounter, with the exception of the earliest ones. 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 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
Windows Installer represented by the following components:- file C:\Windows\System32\Msiexec.exe - directly by the installer application itself;
- file C:\Windows\System32\msi.dll - Windows library Installer;
- Msiserver service, whose settings are stored in the registry key.
If the files are missing, copy them from another system of the same version or from the installation disk. If a registry key is missing or damaged, also move it from working system. To do this, on a working computer, run the registry editor (C:\Windows\Regedt.exe) and find the above section. 
Expand by right click context menu msserver 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 if the RPC service is running ( Remote call procedures) on which it depends. 
You can re-register the installer files and restart the service using special teams, on the command line. For convenience, you can create batch file: Paste the action set 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.
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 your OS using Sfc teams/scannow. You need to enter it into the command line window.
Launch command line You can also do it 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 others. system programs.

In the window that opens, click on the “Run Now” button. The utility will restore correct configuration installer.
It is worth noting that the utility does not work with the eighth version of the operating system.
To begin with, I suggest you figure out what kind of service this is?
Windows Installer Service- is responsible for installing programs on your . And without it, you will not be able to install a program that needs installation on your computer (this only applies to installers in the *.msi format).
And when you try to install, you will get a message with the following content:
. Either Windows is running in Protected Mode or the Windows Installer service is not installed correctly. Contact Support.
There may be several reasons for such an error, and I will try to explain each one to you separately.
Access to the Windows Installer service is denied because you are logged in as a guest.
This means that you are logged into the operating system not as an administrator, but as a guest or with limited entry. And in this case, it is unlikely that you will be able to install anything.
Solution to the problem:
If this is not your computer, or the computer at your work, contact the administrator or owner of the computer and have them give you rights.
But if this is your computer, then a cunning relative lives with you, who has limited your access, and you log in to your own computer without administrator rights. Give him a poke. :box:
The Windows Installer service is disabled.
Well, the problem is already clear, why the hell you can’t install anything. By the way, this is the most common mistake.
Why does the service go down? I don’t know myself, maybe you installed something nasty, or maybe you caught it harmful virus, or, quite likely, someone’s crooked hands are to blame for everything... As for me, these hands are to blame for everything.
IN general reasons maybe a lot. And there is only one solution:
1. Click "Start" - "Run". (Win+R)
2. In the window that appears, enter: services.msc, and press "Enter"
3. In the "Services" window, look for: " Windows Installer". And we do double click mouse.
5. In the window that appears, look at the “General” tab.
6. In the “Startup type” field, select “Manual” if you have another option.
That's it, now the installer should start when you install the program.
If you have looked through everything, but still haven’t found this service, I advise you to look again. Is it enough? And if you are already a hundred pounds sure that there is no such service, then you need to install it.
Windows installer error is one of the most common pop-up problems encountered by users of the Windows operating system.
Reasons for the error
