Fix Office 2013 Keeps Asking for Product Key on Windows 11
Question details
The user needs to resolve an issue where Office 2013 continuously prompts for a product key upon launching applications, despite previously accepting the key.

- Product
- Microsoft Office 2013
- Device & OS
- Windows 11
- Scenario
- Launching an Office 2013 application after a fresh Windows 11 and Office installation.
- Observed behavior
- Office 2013 accepts the product key but fails to save the activation status, repeatedly asking for the key every time an application is reopened.
Ensure you have your genuine 25-character Office 2013 product key ready and verify that your Windows 11 system is fully updated before attempting to re-activate.
Run Office as Administrator to Save the Product Key
Running the application with administrative privileges allows Office to correctly write the activation data to the Windows registry.
Because Office 2013 is older software, it sometimes lacks the necessary permissions to save licensing information on newer operating systems like Windows 11. Launching it as an administrator bridges this permission gap.
Ensure all Microsoft Office applications, including Word, Excel, and Outlook, are completely closed.
Search for Word in the Windows Start menu, right-click the Word application icon, and select Run as administrator.
When the activation prompt appears, enter your 25-character Office 2013 product key and confirm.
Close Word and restart it normally to verify if the product key prompt has been successfully resolved.

Configure the Office Software Protection Platform Service
Ensuring the licensing service runs automatically with a delayed start helps validate your product key properly during application startup.
Perform a Quick Repair of Office 2013
Using the built-in Windows repair tool can fix corrupted licensing files that cause activation loop issues.
