	// This method is called by a client to import one or more conglomerations from an installer
	// package file. Importing a conglomeration from an installer package file conceptually
	// consists of installation of modules, including the registration of the components
	// in those modules, and creating a conglomeration and component configurations equivalent
	// to the conglomeration and the component configurations that were exported to create
	// the installer package file. As a side effect, this method returns implementation-specific
	// detailed results of the registration operation for informational purposes.
	//
	// Return Values: This method MUST return S_OK (0x00000000) on success, and a failure
	// result, as specified in [MS-ERREF] section 2.1, on failure. All failure results MUST
	// be treated identically.
