A regular issue faced is the dreaded “Another version of the product is already installed”, “Your computer has a newer version of MSN Messenger than the one you are trying to install”, ““Your computer has a newer version of Windows Live Messenger than the one you are trying to install”, “The feature you are trying to use is on a network resource that is unavailable” and similar messages.
