How to Reinstall Microsoft Office 2007

Updated April 17, 2017

If Microsoft Office 2007 has been deleted or uninstalled from your computer, it can be reinstalled using a valid product key. This product key can be found on the case that the Office 2007 CD came packaged in. If your system came with the Office 2007 software preinstalled, a sticker containing the product key can be found on your computer. The software is reinstalled using either an Office 2007 CD or by downloading the installation file from the Microsoft website.
