You can install Office on a total of five computers. But what if you buy a new machine? No problem. You can deactivate Office on one computer so you can install it on another.
On your account page, under PC + Mac Installs, click Deactivate next to the name of the computer where you want to deactivate Office.
After you deactivate Office on one computer, you can install it on another.
When you deactivate an install, Office will run in read-only mode on that computer. That means you’ll be able to view and print documents but you won’t be able to edit them or create new ones. If you want to completely remove Office, you can.
