A product key is a unique combination of 25 numbers and letters. The product key is used during Microsoft software installation to "unlock" or to open the product. If you do not enter the product key when you are prompted during the installation, the product may not open until you enter the product key. The product key is typically located on an orange or yellow sticker on the back of the CD case or the DVD case.
To obtain a new product key for your Office program, contact Microsoft and speak to a customer service representative. To do this, visit the following Microsoft Web site:
