I have been trying to re-install Windows Live OneCare after my hard drive was re-formatted. For some reason, after 2 attempts, I haven't been able to finish the installation. Would it be Windows Firewall stopping me? I have Windows Vista Home Professional 64 bit for and OS.
The Windows firewall wouldn't be an issue. Are you installing from the One Care website or are you using a CD? When One Care installation fails is there an error mesage and if so, what is the error message? Without more information I can only suggest the general troubleshooting steps in this post - http://social.microsoft.com/Forums/en-US/onecareinstallandactivate/thread/ba26b781-da18-4ce4-be8c-22647bd5d8fcJim - MVP Windows Live - Forum Moderator - Live One Care - Live Mesh
