DESCRIPTION

This module provides commands for accessing the Microsoft Windows Installer (MSI) component through its COM interfaces. The primary motivation for this module is that although the Installer provides a COM type library, its type library may not be available on the target system. This module provides the required type definitions for the various interfaces.

Creation and Destruction of MSI objects

MSI objects are created through TWAPI's COM interface commands. The Installer object is created through the command

set msiobj [comobj WindowsInstaller.Installer]

Once an MSI object is no longer needed, it must be deleted like any other COM object.

$msiobj -destroy

Note a final call to $MSIOBJ -destroy is required for all MSI objects, not just the top-level Installer object.

Once an MSI object is created, its type library must be explicitly loaded by calling load_msi_prototypes with the object command and the object type.

twapi::load_msi_prototypes $msiobj Installer

Example: List installed products

load_msi_prototypes MSICOMOBJ MSITYPE
Loads the type information corresponding to the MSI type MSITYPE into the COM object command MSICOMOBJ. The sections below describe the various types of MSI objects that can be loaded. When an object of a type is created, it should be passed to load_msi_prototypes along with the type before making any method calls on the objects.
