Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Redeem your Office 2024 product key with a Microsoft account, then download Office while signed in with that same account.
1. Redeem the product key
If this is the first time you are using the 25-character code:
- Go to https://www.office.com/setup.
- Sign in with your Microsoft account, or create one.
- Enter the product key without hyphens.
- Follow the prompts to associate Office 2024 with that account. Remember which account you use—you will need it for installation and future reinstalls. ^1^
If the site says “This product key has already been used,” do not enter it again. The key has already been redeemed; sign in using the Microsoft account that was used when it was first redeemed.
2. Download and install Office 2024
- Go to https://m365.cloud.microsoft/apps.
- Sign in with the Microsoft account linked to your Office 2024 purchase.
- Select Install apps, and then select Install.
- Complete the installation for your device: ^2^
- Windows: Run the downloaded setup file, approve the User Account Control prompt, and wait for “You’re all set! Office is installed now.”
- Mac: Open Finder → Downloads, double-click Microsoft Office installer.pkg, and proceed through the installer.
- Open Word or Excel and sign in with the same Microsoft account to activate Office.
If Office 2024 is not listed
Check the Microsoft account’s Services & subscriptions page:
https://account.microsoft.com/services
If Office 2024 does not appear under your purchased products, you may have signed in with a different Microsoft account. If the key has not been redeemed and is rejected as invalid, contact the seller; Microsoft advises requesting a refund when a separately purchased key does not work or has been blocked. ^1^
