Are you saying your brother has
office 2010 Professional disc and doing. Student Edition and you want to buy another license for that software? It's possible Microsoft will sell you a 2d license for the same
windows 7 professional x64, but not likely. However you can contact Microsoft directly and ask them if they will do that. But you are really just paying for the software a second time....so you may as well just go buy the
microsoft office 2010 cd key again so you can get the license (the license is the product key).
