Errors When installing applications from files with extension. MSI is one of the manifestations of the Windows Installer service (in the Russian-language version - Windows Installer). Such a phenomenon face users of all versions of this OS, with the exception of the earliest. Until now, the problem with the installer is one of the frequent reasons for which users are solved on reinstalling the system. Let's try to figure out how to avoid it. The reason for Windows Installer does not work, maybe the following:
- viral infection, and the removal of the virus does not always solve the problem;
- incorrect installation of Windows updates;
- the protection software fails when, instead of blocking one suspicious MSI file, the installation service is blocked entirely;
- changes in security policies on a computer;
- damage to system files or registry for reasons not related to viruses (removal of installer components, unqualified registry editing, "Curve" software, hard disk malfunction, etc.).
Check the integrity of the Windows Installer structure
Windows installer is represented by the following components:- c: \\ Windows \\ System32 \\ Msiexec.exe file - directly by the installer appointment;
- c: \\ Windows \\ System32 \\ MSI.DLL file - Windows Installer library;
- the MSISERVER service, the parameters of which are stored in the Registry section.
In the absence of files, copy them from another system of the same version or from the installation disk. If there is no registry key or damaged - also transfer it from the working system. To do this, on a good computer, run the registry editor (C: \\ Windows \\ regedt.exe) and find the above section. 
Expand the MSISERVER folder context menu and click Export. Save the file in format.Reg and transfer it to a problem machine. 
Click twice this file and confirm your consent to add data to the registry. Restart the computer. 
If the MSISERVER service is still not started, check if the RPC service works (remote procedure call) from which it depends. 
You can re-establish the installer files and restart the service using a set of special commands, on the command prompt. For convenience, you can create a command file: Insert a set of actions in a notebook and save both with the extension.Bat. To start the file, just double click on it. To make changes to act, click on the desktop and press F5. Check the security settings and access rights
Windows Installer may not work and due to the fact that it blocks the protective software or the operating system does not have the necessary rights. To begin with, we will deal with the software. If you have installed antivirus - temporarily disconnect it. Methods for disconnecting each product, but most often this is done through the antivirus icon context menu in the system tray. Now we will deal with rights. Open the msiexec.exe context menu and expand its properties.
Check the list of groups and users on the Safety tab. Among them, there must be a "system" and the "TrustedInstaller" service, and the last one must have full access to the file and be its owner. The system must have the rights to read and read and execute. 
The TrustedInstaller service first appeared in Windows Vista, so in Windows XP full access must be provided with the system. Everything that is written below relate to versions released later than XP. To check who owner Msiexec.exe, click the "Advanced" button on the same tab. 
In the next window, discover the "Owner" tab. Make the owner of the TrustedInstaller service if something else is specified as it. If you do not have it in the "Change Owner to" list, click the "Change" button, and next - "Other users and groups". 
Enter TrustedInstaller in the field "Enter the names ...", click "Check Names" and OK. Return to the previous window. On the "Existing Permissions" tab, assign TrustedInstaller and the system necessary rights. 
Exactly the same security settings must be at the MSI.dll library. Now check if there are no restrictions for the user "System" to access the following: - system disk (usually drive C);
- temporary folders (this is C: \\ Windows \\ TEMP and C: \\ Users \\ Current user \\ APPDATA \\ TEMP);
- c: \\ Config.msi folder;
- the folder where the MSI file is located from which you are trying to install the program.
The operating system consists of a huge number of programs and services, each of which performs its functions. For example, to install on your computer, Windows Installer is used on your computer - Installer's service for Windows 7. It is responsible for unpacking files and data enclosure to the system registry. Some users when trying to install applications encounter an error "failed to gain access to the service", as a result of which the program installation becomes impossible. This article presents ways to solve the problem. 
Such an error may occur if the relevant service is disabled, system files or records in the registry are damaged. The following are the ways to solve such problems.
SCAN NOW
If, as a result of the action of viruses or system failures, any important system files that are responsible for Installer have been corrupted, you can use a special command to console and eliminate errors. Need to do the following:
After that, try calling the installer again by running the installation of some application. If the problem is not resolved - go to the next point of management.
Services Manager
Perhaps the Installer does not work because of the disconnected service, which is responsible for it. Try to open the manager and turn it on. If you do not know how to do it - follow the instructions:
If there is no option in the list of the desired item, call the command line. How to do this is described above, in the previous section of the manual. In the console you need to enter the "Net Start Msisserver" command and press Enter. If no problems arise, you will see the inscription "Windows installer successfully running".
Export registry
You can also find a copy of a foreign registry section and import it to your computer. The directory you need is called "HKEY_LOCAL_MACHINE \\ SYSTEM \\ CURRENTCONTROLSET \\ SERVICES \\ MSISERVER".
