Some Office 2019, Office 2016, and Office 2013 products come with a product key. If yours did, before installing Microsoft 365 for the first time, sign in with an existing or new Microsoft account and enter your product key at office.com/setup. Redeeming your key is what links your account with Microsoft 365 so you only have to do this once. Already did this? Select the tab below for the version you're trying to install.
Reinstall Microsoft 365
If Microsoft 365 originally came pre-installed and you need to reinstall on it on the same device or a new device, you should already have a Microsoft account associated with your copy of Microsoft 365. This is the account you'll use to install Microsoft 365 following the steps below. If you need to uninstall Microsoft 365 first, see Uninstall Office from a PC or Uninstall Office for Mac.
Note: The steps to install the 2019, 2016, or 2013 versions of Office Professional Plus, Office Standard, or a stand-alone app such as Word or Project might be different if you got Microsoft 365 through one of the following:
Microsoft Workplace Discount Program (formerly known as Home Use Program): If you bought Microsoft 365 for personal use through your company, see Install Office through Workplace Discount Program.
Volume license versions: If you work in an organization that manages your installations, you might need to talk to your IT department. Some organizations have different methods to install Microsoft 365 on multiple devices.
Third-party seller: You bought Microsoft 365 from a third-party and you're having problems with the product key.
You're now ready to install Microsoft 365. Select the tab below for the version you're trying to install.
Remember a one-time purchase version of Microsoft 365 is licensed for one install only.
Your install is finished when you see the phrase, "You're all set! Office is installed now" and an animation plays to show you where to find Office applications on your computer. Select Close. Follow the instructions in the window to find your Microsoft 365 apps. For example depending on your version of Windows, select Start and then scroll to find the app you want to open such as Excel or Word, or type the name of the app in the search box.
If you're unable to install Microsoft 365 see Troubleshoot installing Office for more help.
Tip: If you see an error that says the Microsoft_Office_2016_Installer.pkg can't be opened because it is from an unidentified developer, wait 10 seconds and then try double-clicking the installer package again. If you're stuck at the Verifying…. progress bar, close or cancel the progress bar and try again.
On the first installation screen, select Continue to begin the installation process.
Note: If you want to only install specific Office apps and not the entire suite, click the Customize button and uncheck the programs you don't want.
Enter your Mac login password, if prompted, and then click Install Software. (This is the password that you use to log in to your Mac.)
The software begins to install. Click Close when the installation is finished. If Microsoft 365 installation fails, see What to try if you can't install or activate Office 2016 for Mac.
Click the Microsoft Word icon in the Launchpad.
The What's New window opens automatically when you launch Word. Click Get Started to start activating. If you need help activating Microsoft 365, see Activate Office for Mac. If Microsoft 365 activation fails, see What to try if you can't install or activate Office for Mac.
