MacBook Pro OS x v.10.6 Snow Leopard ERROR installing Internet Security

Hi, I recently purchased the new macbook pro and also got myself the Norton Internet Security.  I have installed the software into my Mac, and I have all these error messages that says I can't update with LiveUpdate, and also, something about a 64-bit kernel / 32-bit kernel message error.  I'm not too sure what it means.  Can someone help me? Does anyone have the same problem?
