You can install Office 365 Home Premium on up to five PC or Mac computers. If you’ve used all five installs and want to run Office on another PC, you can. But first you have to deactivate it on one of the first five computers.
Deactivate Office
On your account page, under PC + Mac Installs, click Deactivate next to the name of the computer where you want to remove an install. (The account page lists the computers where Office is installed and how many installs you have left.)
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.
