I'm getting '...programs not compatible...' error, but don't want to uninstall

I just purchased Norton 360 v5.0 and am getting the classic '...program not compatible... please uninstall, restart...' error message because of McAfee.  Can I avoid uninstalling McAfee (like by disabling it) until I've completed my Norton installation, and am sure it works properly? I figure actively running both will cause problems, but what if McAfee is not running? Thanks for any thoughts on this!   --BAR
