This article applies to Office Home & Business, Office Home & Student, and Office Professional. It doesn't apply to Office programs that are installed from a Microsoft 365 subscription.

If you've already installed Office on multiple PCs and are having trouble activating them, see Change your Office product key.

Select the version below with steps for how to manage multiple one-time purchase installs with the same Microsoft account. 

Tip: When you need to install Office on multiple PCs, it’s easier to manage them if you buy a Microsoft 365 business subscription or purchase a volume license version of Office.

  1. Open an Office app such as Word and sign in with the Microsoft account associated with this version of Office.

  2. Similar to the window screenshot below, a numbered list of all your licenses will appear in the Select Office for this device window. One of your licenses will be pre-selected. Select that one or choose a different license for this device, and then select Next Screenshot of Select Office for this device window

    Tip: Remember, most one-time purchases are only for use on 1 device. Using the screenshot above as an example, this means if you selected Microsoft Office Home and Business 2019 (3), you wouldn't be able to reuse that license by adding it to a different device.

  3. Follow the remaining prompts.
