This article walks you through the process of changing your existing Plus Edition license key to a new or different key. This may be necessary if your organization has consolidated multiple product keys into a single one.
Note: You must have Office Timeline version 3.9.5 or newer for these steps to work. You can check the version of Office Timeline you have installed by pressing Help > About in the Office Timeline tab inside PowerPoint. If you have an older version of Office Timeline, please follow Solution B in this article.
If you have Office Timeline version 3.9.5 or newer, you can deactivate the existing license and re-activate Plus Edition using a new product key by following these steps:
Open PowerPoint and click on the Office Timeline+ tab.
Click Yes when prompted to deactivate your license. This will remove the existing license from your computer and revert Office Timeline to Free Edition mode.
The Upgrade and Activate buttons will appear on the Office Timeline tab after successfully deactivating your machine. Press Activate to open the product activation dialog box.
Paste or type your new product key and press the Activate button to activate Plus Edition.
