Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
This usually happens when the new laptop is picking up the older Office 2019 license already linked to the same Microsoft account instead of the Office 2024 license.
Try this on the new laptop:
- Uninstall all existing Office versions and Office apps.
- Open Control Panel > Programs > Programs and Features.
- Remove any Microsoft Office entries.
- Restart the laptop.
- Sign in to the Microsoft account that was used to activate Office.
- Check whether Office 2024 appears under the account’s Services & subscriptions page.
- Reinstall Office from the Office 2024 entry for that account.
- Use the Install option for the Office 2024 product.
- If Office still opens with the 2019 license, change the product key for that installation if the Office 2024 purchase included a product key.
- For most Office 2024, Office 2021, and Office 2019 versions, no product key is included and sign-in with the linked account is used instead.
- If both Office 2019 and Office 2024 are installed on the same PC, remove the older version first.
- In most cases, Microsoft 365 or non-subscription versions such as Office 2021, 2019, and 2016 cannot run together on the same computer.
- If multiple versions were installed out of order, the later version may need a repair after the older one is removed.
Important checks:
- Make sure both Office installations are the same bitness: both 32-bit or both 64-bit. A mix is not supported.
- If a one-time purchase was installed on multiple PCs using the same Install button, activation can fail on the other PC because that install is tied to one unique product key.
If the Office 2024 license does not appear separately under the Microsoft account, or the install keeps binding to Office 2019 after reinstalling, Microsoft Support is the next step.
