Are you saying your brother has
office 2010 Professional key 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 home premium 32bit, 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 pro 32bit again so you can get the license (the license is the product key).
