New computer will not let me install Windows XP and Office 2007 updates. I appears they are downloaded (I am assuming), but they will not install. There are a mixture for a total of 12. I set Microsoft updates site as trusted. I am running McAfee. Do I need to disable virus checker to get it to work? Would disconnecting my router temporarily help? Cannot find them in applications to install in Add/Remove Programs. Argh - any suggestions would be appreciated. Have never experienced this with previous computers. Thanks.
