Before you start

Ensure you have your 25-character product key handy, verify your internet connection, and confirm that you are logged into the correct personal Microsoft account intended for the subscription.

Solution 1

Verify Account Type and Redemption Details

Ensure you are using the correct Microsoft account type and validating the purchase origin before retrying.

Product key errors often occur when there is a mismatch between the subscription type and the Microsoft account being used.

Confirm third-party purchase

Check your receipt from the third-party retailer to ensure the key was properly activated at the point of sale.

Solution 2Recommended
