I had the misfortune that it failed to install on either my desktop or laptop, connecting through two different networks. This happened with XP Professional and Home editions.
The problem got solved following advice on this page.
If you are having problems installing Writer, Messenger 8.5 or Mail, in particular if the the Windows Live installer disappearing halfway through (after a Windows Vista UAC prompt if enabled), this may help.
- Close all Windows Live applications
- Navigate to C:\Program Files\Windows Live and delete the Installer folder
- Navigate to C:\ProgramData and delete both Windows Live Installer and WLInstaller directories if you have them.
- Reboot (important!)
- Reinstall the application you want to install
(Step 3 is not for XP and I didn't do anything here. You may read the full post and discover more about the problem and a link to the official solution, none of which I have tried.)
