Hello, Anthony
Thank you for visiting Microsoft Community.
It appears you have purchased Office Home 2024 and require assistance with application activation. Since you possess a valid product key, kindly proceed to https://setup.office.com/redeem/enter-key to redeem your key by associating it with your designated Microsoft account.
Subsequently, please visit ***account.microsoft.com/services*** using the same Microsoft account. Locate your license section and select the "Install Office" option in the upper right corner to download the appropriate online installation package for your preferred language and operating system version. Upon completing the installation, simply sign into your licensed Microsoft account within the Office application, which will automatically recognize and activate all premium features.
I trust this guidance will prove beneficial. Should you encounter any difficulties during this process or wish to share updates regarding your progress, please don't hesitate to inform me.
Best regards
Kai Ho | Microsoft Community Support Specialist
