Your company has a volume licensing agreement with Microsoft for using Windows XP Professional on 50 client computers. You receive a volume license product key from Microsoft that must be used to install Windows XP Professional on the computers. Since you have lost the Windows XP Pro CD that was sent by Microsoft, you must purchase a new copy of the installation disc. During the Windows XP Pro setup using the attended installation method, you type the volume license key and the setup displays an error message that states “Invalid product key.” How should you proceed?
