I purchased Office Ultimate 2007, but there was NO product key in the package. The only number was for "Office Ultimate Hero 2007" but the software install will not accept the number as valid. (Delivery Note # 2790186086) consequently, I cannot load the software unless I use it for only 25 times. WHERE CAN I GET MY PRODUCT KEY????
Perhaps from the person/persons you bought the software from.
If it came in a box, when you open it, take a look at be back side of the box. The initial requester should always write the last response !!!
