Can I use Office Home and Student on multiple computers?

Download Article

This wikiHow teaches you how to install Microsoft Office on a different computer than the one you've been using. If you have a subscription to Microsoft 365 (formerly known as Office 365), you can use Office apps on up to 5 devices at once, which means you won't need to deactivate your other installations. But if you have a non-subscription version of Office 2019 or Office 2016, you'll need to install or activate Office on the new computer (usually by telephone), and then deactivate it on the old computer.

Things You Should Know

• To transfer Microsoft Office to a new computer, you'll need to deactivate it on your old computer.
• You'll need to call the product activation number to activate Office on your new device.
• If you have a subscription to Microsoft 365, you won't need to deactivate your device.

1. 

   1

   Visit https://www.office.com on the new computer. You can use any web browser, such as Edge, Safari, Firefox, or Chrome, to view the Office website.

   • Use this method if you do not have a Microsoft 365 subscription and want to transfer already-activated copy of Office Home & Business, Office Home & Student, or Office Professional to a new Windows PC.
   • Since your license allows you to have Office installed on one computer at a time, you'll first install Office on the new computer, activate by phone, and then remove the applications from your old computer.[1]

   Sign in to your Microsoft account. Use the account information you use to sign in to Microsoft products, such as Outlook.com, Live.com, or Hotmail.com. If you use Office through your work or school, you may need to use your work or school account to sign in.

13. 

    13

    Enter the confirmation ID and click Next. This is the number the recording or agent reads to you after providing your installation ID. Once you do this, Office will be active on the new PC.

   Install the latest macOS updates on both computers. This ensures a smooth transfer between the two Macs. On both Macs, click the Apple menu at the top-left corner of the screen, select System Preferences, click Software Update, and then select Software Update if it's available.[2]

   • Use this method if you do not have a Microsoft 365 subscription, but instead have a license for Office 2019 or 2016.
   • As of the release of Office 2016, your product key is tied to your Microsoft account. Because of this, you won't need it to reinstall Office on another computer.

2. 

   2

   Make sure the old Mac has a computer name set. The computer on which Office is already installed must have a "computer name" set to use the Migration Assistant. Here's how to check:

   • Click the Apple menu and select System Preferences.
   • Click Sharing.
   • If the "Computer Name" field is blank, enter a name now. It can be anything you want, such as "My Old Mac."

3. 

   3

   Connect the Macs to each other. If both Macs are running the latest version of macOS (or even just High Sierra or later), just place them close together and enable Wi-Fi on each.[3] If either Mac is running El Capitan or earlier, connect both computers to the same Wi-Fi or Ethernet network.

   • If you've backed up your Microsoft Office installation to another drive using Time Machine, you can just connect the Time Machine drive directly to the new Mac instead.

4. 

   4

   Open Migration Assistant on the new Mac. To do this:

   • Click the Finder icon (the two-toned face on the Dock).
   • Double-click the Applications folder.
   • Double-click the Utilities folder.
   • Double-click Migration Assistant.
   • Click Continue.

5. 

   5

   Select "From a Mac, Time Machine backup, or Startup disk" and click Continue. It's the first option in the list.

6. 

   6

   Click Continue. Now you'll perform the next step on the Mac that already has Microsoft Office installed.

   • If you're using a Time Machine backup, skip to Step 10.

7. 

   7

   Open Migration Assistant on your old Mac. This is the Mac that already has Office installed. You'll find it in the Applications folder under Utilities.

8. 

   8

   Click Continue.

9. 

   9

   Select "To another Mac" and click Continue. Now you'll switch back to the new Mac.

10. 

    10

    Select your old Mac or Time Machine backup drive and click Continue. Depending on how you're transferring files, you may have to complete one of these steps:

    • If you see a security code appear, verify that the same code appears on the old Mac, and then click Continue.
    • If you are asked to select a backup to transfer information from, select the latest backup, and then click Continue.

11. 

    11

    Select the information you want to transfer to your new Mac. Since Microsoft Office is a set of applications, check the box next to "Applications." You may also want to copy other information, such as your user account, your settings, and/or other files and folders.

12. 

    12

    Click Continue. This begins the process of copying Microsoft Office and other applications to your new Mac. Once the migration is complete, you'll find Microsoft Office in your Applications folder.

    • If you get an activation error when opening Office on your new Mac, click I want to activate the software by telephone on the Activation Wizard, select Next, and then follow the on-screen instructions. Once Office is activated, uninstall it from your old Mac.[4]

13. 

    13

    Open any Office app on your new Mac. This can be any Office app, such as Word or Excel. You'll find your Office apps on the Launchpad.

14. 

    14

    Activate via telephone if you get an activation error. Since you migrated Office from your old Mac, you should be able to use Office without any trouble. If you get an error about activation, you'll need to perform these steps to activate over the telephone:

    • On the Activation Wizard, select I want to activate the software by telephone and click Next.
    • Select your region to view the Product Activation Center phone number for your area.
    • Call the number and provide the "Installation ID" you see under "Step 2."
    • Type the confirmation ID provided by the phone service into the blank under "Step 3."
    • Click Next and follow the on-screen instructions to activate.

15.

    Remove Office from your old Mac. Now that Office is activated on the new Mac, it'll no longer work on the old one.[5] To uninstall Office on the old Mac:

    • Click the Finder icon (the two-toned smiley face) on the Dock.
    • Double-click the Applications folder.
    • Hold down the Command key as you click each Office app.[6] Make sure you select all of the Office apps, which all begin with the word "Microsoft."
    • Hold down the Control button as you click any of the selected apps. A menu will expand.
    • Click Move to Trash to uninstall OfficeYou can then empty the trash to free up hard drive space.

  If you purchased your copy of Office as a digital download, you can find the product key by checking your order confirmation email or signing into your Microsoft account. If you have an older version of MS Word and have lost the original packaging with the product key on it, you may be able to extract the product key using a variety of key extractors that you can download from the web.
