I looked through the box again and I finally found the Microsoft Office MPI card. It was all the way at the bottom of the box and under one of the cardboard flaps. Thans for your help.
Hello, I purchased a new Dell XPS 8500 computer with Microsoft Office 2010 Home and Business. The packing slip with the computer shows two items in this shipment: 225-4158 XPS 8500 Fast track config38 and 421-8669 Microsoft Office Home and Business Kit, SW,OFCHB-2010T,MPI,ENG,DAO. I have looked everywhere in the box the computer shipped in and I cannot find the Microft Home and Office kit and I cannot activate office without the MPI card. I received this order on 1/24/2013 and the box was undamaged and still sealed with Dell security tape. Should an office kit have been included and MPI? Thak you for your help.
