1 care already been activated in my first PC since 15 Nov 2008 . Now I failed to install it in the second PC , Installation is rejecting my windows live ID . Thanks
You are most likely using the incorrect Live ID. Go to the computer where One Care is already activated, open One Care>Help>About Windows Live One Care and you will see the Live ID associated with your One Care subscription.Jim - MVP Windows Live - Forum Moderator - Live One Care - Live Mesh - Microsoft Security Essentials
