1. Introduction to Microsoft Windows Installer components:
As one of the components of Win2k/WINXP, Microsoft Windows Installer is a tool dedicated to managing and Configuring software services. It is provided as an additional product under Win95, Win98, winme, and winnt4, 0, allowing users to effectively install and configure software products and applications. The new installer provides new features for software products, such as the use of command lines to install the product and increase user customization.
Windows Installer software installation technology. This technology includes a 32-bit Windows Installer server and a new package file format for storing configuration and installation information.
Windows Installer is not only an installer, but also an extensible software management system. Windows Installer manages software installation, adds and deletes software components, monitors file recovery, and maintains basic disaster recovery through rollback.
In addition, Windows Installer supports installing and running software from multiple sources, which can be customized by developers who want to install custom programs.

Ii. Functions of Windows Installer include:
? Restore the computer to the original state when installation fails: Windows Installer tracks all changes made to the system during program installation. If the installation fails, the installer can restore the system to its initial state. This is called "rollback ".
? Helps prevent conflicts between programs in specific forms: programs being installed or uninstalled may cause problems with another program installed on the computer, or even cause the computer to stop responding (suspended ). The installer can enforce some installation rules to prevent installation operations from updating the dynamic link library (DLL) files shared by existing programs, or a conflict occurs when the uninstallation operation deletes the DLL files shared by another program.
? Diagnose and repair corrupted programs: the program can require the installer to determine whether the installed program lacks files or whether the files are damaged. Then, it can require the service to copy the lost or damaged files again as needed to repair the program.
? Reliable uninstall of existing programs: installer can reliably Uninstall any previously installed programs and delete all associated registry entries and program files, except for files and registry entries shared by other installed software.
? Supports on-demand installation of Programs: You can instruct the installer to first install the minimum subset of programs. Then, when you use the feature that requires additional components for the first time, the additional components are automatically installed.
? Supports unattended program installation: installer supports script installation Based on administrator instructions.
The Windows Installer technology is divided into the following two parts, which work together: the Client installation service (msiexec.exe) and Microsoft software installation (MSI) package files. Windows Installer uses the information contained in the package file to install the program.
The msiexec.exe program is a component of Windows installer. When the installer calls msiexec.exe, it uses MSI. DLL to read the package (. MSI) file, apply any conversion (. MST) file, and merge the command line options provided by the installer. The installer executes all installation-related tasks, including copying files to the hard disk, modifying the registry, creating shortcuts on the desktop, and displaying a dialog box when necessary to prompt users to enter installation preferences.
After Windows Installer is installed on a computer, it changes the file type of the registered. MSI file so that when you double-click the. MSI file, msiexec.exe is run.
Each MSI package file contains a relational database that stores the commands and data required to install or uninstall the program in various Installation Schemes.
