If you need to reinstall Office apps in your Office Pre-installed PC (for corporate), we recommend that you uninstall Office first. After you've uninstalled Office, follow the steps below.

Important: Office perpetual products included on the Office Pre-installed PCs (for corporate) in Japan do not require a personal Microsoft account to activate the Office apps.

Reinstall Office

The reinstallation steps you follow will depend if your purchased Office Pre-installed PC includes a product key card or a digital Office product.

Select the correct tab for how you want to reinstall Office.

Office pre-installed PCs with an Office product key card package included had been sold for corporate until year 2023. If you have a product key card included with your device, follow these steps.

Reinstall Office from the "Office Setup" site

  1. Go to https://setup.office.com and select Get Started button

  2. Sign into the site with your Microsoft account

  3. Enter the product key into the Product key field and select Next button

  4. Check the valid Office product name is displayed in the next screen

  5. Select a language from Language menu and select Redeem button

  6. Select either Download 64 bit or Download 32 bit button to get an installer

  7. Run the installer to install the Office apps

  8. When the installation is finished, start an Office app, like Word

    (If you can't find the Office apps, see Can't find your Office apps?)

  9. Accept the license agreement when prompted. Office is ready to use.

Note: A Microsoft account is required to log in this site. But it recognizes that the product key you enter is a device-based license key, so it will never be linked to your Microsoft account if you will obtain an Office installer from this site.
