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 invoked by clicking on the file with the right mouse button. There is no such option for MSI packages, but it can be added through the Registry Editor.

Instructions

Open the Run dialog from the start menu or by pressing the Win + R keyboard shortcut. In the window that opens, write regedit and press Enter. The Registry Editor will start. Confirmation of starting the editor may be required depending on your User Account Control settings.

Go to the HKEY_CLASSES_ROOT \ Msi.Package \ shell branch. Right-click 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 to "runas" (no quotes needed).

In the window on the right, double-click the "Default" key with the left mouse button or right-click once and select "Change ..." In the empty value field, enter "Run as Administrator". Confirm the changes by clicking the OK button.

Now right click on "runas" and select the create partition option again. Create a subkey named "command" (without 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.

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

Causes of Windows Installer crashes

The reasons for Windows Installer not working can be the following factors:

1. Viral lesion system files... At the same time, cleaning the OS does not always solve the problem.
2. Incorrect installation of updates.
3. Incorrect editing of the registry, removal of installer components.
4. Antivirus blocking .msi file
5. Changing the PC security policy.

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

Checking the integrity and health of files

Windows Installer consists of the following components:

• The msiexec.exe file, which is located on the "C" drive in the "Windows" and "System32" folders.
• The msi.dll file, which is nothing more than an installer library.
• The Msiserver service, whose parameters are located in the registry editor key at 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 that there are no unnecessary values. The correct list is shown in the photo.

If the section is missing or some files are missing, copy the elements on the working system and, by right-clicking, select "Export".

Select the location to save the files and write 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 open 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 see that the user has full access to the service.

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

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

Checking the integrity of the Windows Installer structure

Windows Installer is represented by the following components:

• file C: \ Windows \ System32 \ Msiexec.exe - directly by the installer application itself;
• the file C: \ Windows \ System32 \ msi.dll - the Windows Installer library;
• by the Msiserver service, whose settings are stored in a registry key.

Before diagnostics, 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, workable system). Also open the list of services (press Windows + R and enter the command services.msc in the "Open" line of the "Run" application). Search for "Windows Installer" and make sure it starts. If there are no files, copy them from another system of the same version or from the installation disc. If the registry key is missing or damaged, also transfer it from the production system. To do this, on a working computer, start the registry editor (C: \ Windows \ Regedt.exe) and find the above-named section. Expand the context menu of the msiserver folder by right-clicking and click the "Export" item. Save the file in .reg format and transfer it to the problem machine. Double-click this file and confirm your consent to add data to the registry. Reboot your computer. If the Msiserver service still does not start, check if the RPC (Remote Procedure Call) service it depends on is running. You can re-register the installer files and restart the service using the set special teams, on the command line. For convenience, you can create a batch file: paste the set of actions into notepad and save as with the .bat extension. To run the file, just double click on it. To make the changes take effect, click on the desktop and press F5.

Checking security settings and access rights

Windows Installer may not work either due to the fact that it is blocked by security software or the operating system does not have the necessary rights. First, let's figure out the software. If you have an antivirus installed, temporarily disable it. Each product has its own disabling methods, but most often this is done through the context menu of the antivirus icon in the system tray. Now let's get into the rights. Open the context menu of Msiexec.exe and expand its properties. Look at the list of groups and users on the Security tab. Among them must be "System" and the service "Trustedinstaller", 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, you must give the system full access. Everything written below applies to versions released after XP. To check who the owner of Msiexec.exe is, click the Advanced button on the same tab. In the next window, expand the "Owner" tab. Take ownership of the Trustedinstaller service if specified otherwise. If it's not in the Change Owner To list, click the Change button followed by 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 required rights to the 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 already deal with it.
