Product key not recognize, purchase from Harvey Norman

The error TokenNotFound with the message “Sorry, we don't recognize the product key you entered” indicates that the product key is either being entered on the wrong site, has not been activated by the retailer, or is not a valid Office product key.

Follow these steps:

1. Confirm the correct site for Office product keys
   • For Microsoft 365 or Office product keys, redeem only at:
     • Office.com/setup (sign in with a Microsoft account, then enter the 25-character code and select Next).
   • Do not use the Windows Activation or gift card redemption pages for an Office product key.
2. Check for typing mistakes
   • Carefully re-enter the 25-character key and watch for commonly confused characters:
     • B vs 8
     • G vs 6
     • O vs 0
     • Q vs 0
     • VV vs W
   • If the purchase included a confirmation email, copy and paste the key from that email instead of typing it.
3. Verify the product type
   • Ensure the key is specifically for Microsoft 365/Office, not for:
     • Windows (often printed on a sticker on a PC), or
     • Another Microsoft product (e.g., Xbox, gift card, or a different Office version).
   • Office product keys are not interchangeable between versions (for example, an Office 2010 key cannot activate Microsoft 365 or Office 2024) or between suites and single apps.
4. Check if the retailer activated the key
   • If the error persists and the key is definitely typed correctly, the retailer may not have activated the key at point of sale (KEY_NOT_ACTIVATED scenario).
   • Return to Harvey Norman with proof of purchase and request that they activate the product key or provide a replacement.
5. If the key is blocked or invalid
   • If the key has been blocked or is no longer valid, it will not work even when entered correctly.
   • In that case, contact the seller (Harvey Norman) and request a refund or a new, valid key.
   • If the seller does not resolve the issue and a valid Office license is still needed, purchase Microsoft 365 or Office directly from Microsoft or another trusted retailer.
6. Region and country checks
   • If the key was purchased in a different country/region than where it is being redeemed, region errors such as “This product key isn't meant for your region” can occur.
   • If a region-related message appears, contact Microsoft support for assistance.

After the key is successfully redeemed at Office.com/setup, the Office product is tied to the Microsoft account used. Future installs and activation should be done by signing in with that account, not by re-entering the product key.
