Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
If this is a Microsoft 365 subscription, install Office on the second computer by signing in with the same Microsoft account used on the first computer:
- On the second computer, open a browser and go to https://account.microsoft.com/services.
- Sign in with the same Microsoft account tied to the Microsoft 365 purchase.
- Find the Microsoft 365 subscription and select Install.
- Run the downloaded setup file and complete the installation.
- Open an Office app and sign in when prompted to activate it.
If the install limit has been reached, deactivate an older installation first. For Microsoft 365 for business, Office can be activated on up to five computers per user. Deactivation does not remove Office from that computer, but it cannot be used there until reactivated.
If installation is very slow, use the offline installer:
- In the install window, select Offline installer from Choose a version.
- Select the language and choose Install.
- Open the downloaded IMG file from the Downloads folder.
- Open the virtual drive that appears in File Explorer and run the installer.
For one-time purchase versions of Office, installation rights depend on the product edition.
