If you are like me and obsessed about security, then you might find that your PC is sitting behind a firewall with no direct outbound web access. That is other than through an proxy server of some sorts like the Linux based squid.
What happens is the Window Live Installer (WLInstaller.exe) searches your computer for installed Windows Live programs and then fails to check for and download the new versions. Why? Because it ignores the default proxy settings you’ve configured under Internet Explorer. To solve it simply execute proxycfg -u to import proxy settings from current user’s Microsoft Internet Explorer manual settings and try the installer again.
