I bought 3 copies of a Microsoft Office Home & Business 2013 in french (Microsoft part number T5D-01575) for a customer. At the last minute, the customer asks me to install his computers in english instead. With Windows 7, there's absolutely no problem installing and activating Windows in english and using a french product key, and vice versa, they are absolutely interchangeable.
With the fact that I have to download Office 2013 from the Internet, does anyone know if I can download, install, and activate Office 2013 in English using a French product key? Or did I just get myself shafted with $750 of unusable licenses and be forced to buy it again in English?
