Download and install or reinstall Office 365 or Office 2019 on a PC or Mac

Before you begin, make sure your PC or Mac meets the system requirements.

Office for home Some Office for home products come with a product key. If yours did, before installing Office 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 Office so you only have to do this once. Already did this? Go to Step 1.

Office for business If your Office for business subscription plan includes the desktop version of the Office apps you won't see an option to install it unless someone in your organization assigned a license to you. Learn how to check this in What Office 365 product or license do I have? Office 365 admins responsible for this, see Assign licenses to users.

Note: *Some versions of Office don't have an associated Microsoft account, or work or school account, or you may need to redeem your product key in a different way. For Office Professional Plus 2019, Office Standard 2019, or a stand-alone app such as Word 2019 or Project 2019 the steps to install Office depend if you got Office through the following:

Microsoft HUP: You bought Office for personal use through your company and have a product key, see Install Office through HUP.
Volume license versions: IT departments might use a different method to install Office for their organization. Talk to your IT department for install help.
Third-party seller: You bought Office from a third-party and you're having problems with the product key.

  In this case, if you have 32-bit, but you want to install the 64-bit version you'll need to uninstall the 32-bit version first. Once that's done sign in to this location again and select Other install options, your language, and then under Version select Advanced > 64-bit or 32-bit, and then select Install.

Account questions:

I don't have a Microsoft account yet, or I forgot my username or password

Before you can install Office 365 orOffice 2019 you need to associate it with a Microsoft account, or work or school account.

If you have an Office for home product and bought Office at a retail store or online store, but don't have a Microsoft account, it's possible you haven't redeemed your product key yet (if you got one), or you missed the step for linking your recent purchase with an account. Do the following to link an account with Office.

For an Office for home product, go to office.com/setup and create a new Microsoft account or sign in with an existing one, then follow the remaining steps on that page such as entering your product key (if you have one). Your account is successfully associated with Office when you see the page, My Office Account followed by your Microsoft account email address, and a button to install Office. Select the PC or Mac tabs above to help you with the rest of the install process.
