The subscription to my last version of Live OneCare lapsed about a month ago. I was at the computer store today and bought another copy of the software. It doesn't want to install. I'm thinking that I need to uninstall the older version, but would like to know for certain before I do that. Any definite advice. I'm not looking for hunches. And for the record, I think I get better support from my ex-wives. I'm kind of sorry I didn't buy someone else's software at the moment.
