I have Home & Student on my computer and was recently given an Office Professional 2010 disk by Microsoft. When I run the setup file on the Pro disk, it opens a window for changing the installation of the Home & Student installation (Add/Remove features, Repair, Remove, Enter Product key.) If I choose Remove, will all of my settings be removed, too? Do I really have to remove the Home & Student version before I can install Professional? If not, how do I get the Professional version to go through setup?
