Windows Messenger Is No Longer Available
Windows Vista does not include the APIs for Windows Messenger. They are included with Windows Live Messenger to ensure continued support for applications that use the Windows Messenger APIs. You can download Messenger from the Windows Live Messenger site.
Applications developed with the Windows Messenger SDK are compatible with Messenger; however, Messenger does not support script that uses Windows Messenger objects. Applications that require Messenger functionality should be developed with the appropriate Live SDK. More information about the Live SDKs can be found on Windows Live Dev.
