When i start my computer, Microsoft office asks for a valid product key. see below for details?

The box that apears asks for a 25 digit product number located on cd case or certificate of authenticity. I don't recall having either. When I X out of this box, another apears asking for that number. After several atempts closing these boxes, they are are gone until the next start up, or I can work on top of them. This is annoying. Any ideas to solve the problem or aquire this number?

How did you install it in the first place as you have had to put the key in when installing it or any MS product as the key number will usually be on the package the CD came in or on the CD itself? If you don't use it then just remove it from your computor by double clicking on my computor/control panel........in control panel click on add/remove and remove it

Anyway here is link to some free utilities to locate the number on your pc if a number was used when you installed MS Office and you no longer have the case/sleeve MS Office came in
