If this is the first time you're installing Microsoft 365 you may have some setup steps to do first. Expand the learn more section below.
However, if you're reinstalling Microsoft 365, and you've already redeemed a product key and have an account associated with Microsoft 365, then go to the section sign in to download Office.
Install Microsoft 365 for the first time
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.
