Install on 2 devices

An eligible Microsoft 365 business license lets the same licensed user install and activate the apps on both a laptop and a desktop.

Microsoft 365 Apps for business, Business Standard, and Business Premium permit each licensed user to install Microsoft 365 on up to five PCs or Macs, five tablets, and five phones.^1^

Install on each computer

Repeat these steps separately on the laptop and desktop:

1. Go to the Microsoft 365 Apps portal at https://m365.cloud.microsoft/apps.
2. Sign in with the same work or school account to which your business license is assigned.
3. Select Install apps.
   • With a work or school account, select Microsoft 365 apps.
   • For Business Premium, the option may appear as Premium Microsoft 365 Apps.^2^
4. Complete the appropriate installation below.

Windows

1. Open the downloaded installer by selecting Run, Setup, or Save File, depending on the browser.
2. If Windows displays the User Account Control prompt, select Yes. The Windows account must have local administrator rights.
3. Wait for “You’re all set! Office is installed now,” and then select Close.
4. Open Word or Excel from the Start menu, accept the license agreement, and sign in with the licensed work or school account if prompted.

macOS

1. Open Finder → Downloads.
2. Double-click Microsoft Office installer.pkg.
3. Select Continue, accept the license agreement, and select Install.
4. Enter the Mac administrator password if prompted.
5. When installation finishes, select Close.
6. Open Word from Launchpad and select Get Started to complete activation.

The complete Windows and Mac procedures are documented here.^3^

If “Install apps” is missing

The account must have a Microsoft 365 license assigned to it, and the subscription must include the desktop applications. If this is an organization-managed account, ask the Microsoft 365 administrator to check the user’s license assignment. Business subscriptions are purchased per user, and an administrator assigns a license to each person.^1^

Do not redeem the product key again on the second computer; install and activate by signing in with the licensed account.
