Here at Liveside, we have been getting a few requests for the individual installers for Wave 3. This could be because they don’t want to upgrade Messenger (ie, they only want to upgrade Writer, for example), or they’re trying to install on an OS that the Windows Live Installer deems “unsupported.”
UPDATE: Scott should know that hosting redistributed Microsoft property is a violation of the license agreement. He may want to update you on how to install individual Wave 3 products, as we did when the installer came out, but we can’t be running our own little Microsoft download center here, sheesh. We never want to support getting any software anywhere but from the original, and legal, source. You can get the Windows Live Wave 3 installer from http://download.live.com/.
