Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
- Redeem the product key if Office 2024 has not been redeemed yet. Enter the 25-character key on the Office product key redemption site for the product, then complete the redemption using the Microsoft account that should own Office.
- After redemption, install Office 2024 from the Microsoft account that is linked to the license:
- Go to the Services & subscriptions page.
- Sign in with the same Microsoft account used to redeem or purchase Office 2024.
- Find Office 2024 and select Install.
- If Office 2024 was already redeemed, do not enter the key again. A redeemed key is used once, and reinstalling is done by signing in to the Microsoft account that already has the license.
- Remove Microsoft 365 or any Office trial to avoid activation conflicts:
- Open Settings > Apps > Installed apps on Windows 11.
- Uninstall Microsoft 365, Office Trial, or other existing Office versions.
- Restart the PC.
- Run the Office 2024 installer that was downloaded from Services & subscriptions.
- Open Word or Excel after installation and sign in with the same Microsoft account. Activation should complete automatically. In File > Account, the product should show as activated for the Office 2024 license.
If Office does not appear under Services & subscriptions, the product key was likely redeemed with a different Microsoft account. Sign in with the account originally used during setup.
For newer Office versions, most Office 2024 installs do not require entering a product key inside the app. They activate by signing in with the account already linked to the license.
