You can transfer Microsoft Office 2013 to another computer and activate it with the old license once every 90 days. Note that Microsoft allows you to transfer the software sooner if your hardware fails. All Office 2013 licenses are transferable, so you need to just deactivate the install on the old computer -- if you don't have any more installs left -- and then install and activate Office on the new PC. Licenses can be deactivated from your Microsoft account with just a few mouse clicks. Keep in mind that you are required to uninstall Office from the old computer when you deactivate it.
Deactivating and Uninstalling Office
Log in to your Microsoft account and then click the "Deactivate Install" link next to your computer's name in the Install Information section. Confirm your action to deactivate Office.

The product key contains 25 characters and can be found on the card that came inside the Office 2013 package.

If you purchased and downloaded the Office suite online, the product is added to your Microsoft account automatically; you don't need to input the product key.
All Microsoft Office 2013 suites can be installed on a single PC and for a single user. Microsoft Office 365 Home can be installed on up to five PCs or Macs.

You don't need to deactivate an install if you have at least one unused install. Just click the "Install" button to install Office on another computer.
