Have you done as it asks and used Windows Update to downloaded the latest Windows Installer?

I'd suggest there's a LOT more updates to do as well if you don't have the latest version of Windows Installer.

You should ensure that your computer is properly patched and up to date with everything otherwise you are taking unnecessary security risks.

Run Windows Update via Internet Explorer (Tools->Windows Update) and then install everything it asks you to (will probably take several hours and several restarts)

One of the things it will prompt you to install is Windows Live Essentials....which is the suite that contains the new WLM
