Hello, thank you for reaching out to Microsoft Q&A.
Since you purchased from the Microsoft Store, the license might be digital, so you no longer need a product key to activate it. Could you please go to your Microsoft account’s Services & Subscriptions page and check whether the Office Home 2024 product is already associated with your account?
https://account.microsoft.com/services
If the product is associated with your account, you’ll see an option to install it on your device, as shown in the screenshot.

If you have received a product key in an email, you can redeem it using the link below.
