To retrieve Windows Live Messenger 2009's msi, you need to install the component you need (Messenger in this case), unhide all system files and folders and go to %CommonProgramFiles%\Windows Live\.cache\ . There you will be able to find all msi which were installed on your system. Messenger.msi won't work as standalone setup, to run application successfully you will need to install other components, such as contacts.msi, crt.msi etc. depends on system.
If you deploy WLM 2009, you need .net framework 3.5 installed on the computer. If it's not installed, you'll get an error telling that it's not installed properly.
