Ms office 2013 product activation failed

I have fixed my problem by reseting Microsoft Settings.

If you are experiencing activation issues with Microsoft Office 2013 and receiving a "product activation failed" message, here are some steps you can try to resolve the issue:

Verify Internet Connection: Ensure that your computer has a stable internet connection. Microsoft Office 2013 requires an active internet connection for activation.

Check Date and Time Settings: Make sure the date and time settings on your computer are accurate. Incorrect date and time settings can sometimes cause activation failures.

Use the Correct Product Key: Verify that you are entering the correct product key during the activation process. Check the product key you have and ensure it matches the version and edition of Microsoft Office 2013 you are trying to activate.

Activate by Phone: If online activation is not working, you can try activating Office 2013 by phone. During the activation process, select the option to activate by phone, and follow the on-screen instructions. You will be provided with a phone number and a set of numbers to enter. Contact the Microsoft Activation Center via phone, provide the required information, and follow the instructions provided to complete the activation.

Uninstall and Reinstall Office: If all else fails, you can try uninstalling Microsoft Office 2013 from your computer and then reinstalling it. After reinstalling, attempt the activation process again using the correct product key.
