Hello K Chin,

Thank you for posting on Microsoft Q&A forum

To better understand your issue, I need to know which version of Office does your key belongs to, is it Office 2016, 2019 or 2021?

How old is this product key?

Feel free to reply back to this post and update me on your issue, I'll be happy to help.

This is not for Office but for NERO which I downloaded from the Microsoft store and paid Microsoft for the license

If your old Office license key is not being recognized, it could be due to several reasons. Here are some steps you can take to troubleshoot the issue:

Check Compatibility: Ensure that the Office version you are trying to activate matches the license key you have. For example, a key for Office 2016 will not work with Office 2019.
Verify the Key: Make sure that you are entering the key correctly. Double-check for any typos or errors in the key entry.
Repair Office: You can try repairing your Office installation. To do this:
- Go to Control Panel > Programs > Programs and Features.
- Select your Office product and click on Change.
- Choose the Repair option and follow the prompts.
Reinstall Office: If the above steps do not work, consider uninstalling and then reinstalling Office. This can sometimes resolve activation issues.
Contact Support: If you still encounter issues, it may be necessary to contact Microsoft Support for assistance with your license key.

These steps should help you resolve the issue with your old Office license key not being recognized.
