Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Hi Georgia,
This issue can occur if the Desktop Experience component has previously been installed and uninstalled. To provide appropriate troubleshooting steps to resolve your concern, we’d like to ask which Updates are installed on the device. Is it Office Update or Windows Update?
In the meantime, if you still have the Product Key of your Office with you, we suggest that you uninstall and reinstall your Microsoft Office 2013 applications. To do this, follow the step by step instructions provided in this article.
We will wait for your response.
