"you already have a different build flavor of windows live"

Got this message this morning when Windows requested to do updates -- clicked links for help, but they led nowhere -- too old? Got an error message yesterday too fleeting to quite catch, that said I had multiple errors; the day before that, Java asked permission (on startup) to install updates, then disappeared. Clearly, I kinow nothing about any of this, but am trying to start a home-based business on the internet, so I need my computer! Grateful for any help offered!
