Hi, we have recently purchased Microsoft Office for the Mac and installed it on my wife's macbook, replacing an old version. The reason was that the old copy used to block her use of it in university due to it saying that their were other users using it at the same time. So we installed it, waiting for it to ask for a product key but it didn't at any time...? Consequently now when my wife tries to use it in uni the same problem occurs. We have product keys coming out of our butt from the original box but no way of entering them. I have tried to 'register online' with windows but the website simply isn't working. It sounds a real basic thing that I am just missing out on but could do with little help please. You have helped me lot in the past and hope that my first post will be just as successful.
