Deactivate an installation on either a PC or a Mac
If you've already installed the latest version of Office with Office 365 on five computers that you use and you want to install Office on a sixth computer, you can do that by first deactivating an installation on one of your current computers.
Go to Software > Office. Click Deactivate next to the computer you want to deactivate the installation from.
Troubleshoot your Office installation
When you're installing, you may get a "Something went wrong...” error. Or, if you get some other error, see General troubleshooting for installing Office 2013 and Office 365.
After you have Office installed, try creating a few documents. If an Office program looks blurry, displays as all black or all white, the screen flickers, or looks different on different computers, see Office 365 doesn't look right.
You can install the latest version of Office on up to five computers that you use. After you've completed the installation, make sure you have automatic updates turned on.
Depending on your operating system, here's what Office includes
- Office on your PC includes Access, Excel, OneNote, Outlook, PowerPoint, Publisher, and Word.
