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

Office 2019 Office 2019 for Mac Office 2016 Office for business Office 365 Admin More…

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 business product or license do I have? or if you’re an Office 365 admin, see Assign licenses to users.

Note: *Some versions of Office such as Office Professional Plus 2019, Office Standard 2019, or a stand-alone app such as Word 2019 or Project 2019 don’t have an associated account. The steps to install these versions can be different depending if you got Office through one of the following ways:

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 people in 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.

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

Sign in to download Office

1.Go to www.office.com and if you’re not already signed in, select Sign in.

2.Sign in with the account you associated with this version of Office. This account can be a Microsoft account, or work or school account. I forgot the account I use with Office

3.After signing in, follow the steps that match the type of account you signed in with.

You signed in with a Microsoft account

a.From the Office home page select Install Office.

You signed in with a work or school account

a.From the Office 365 home page select Install Office apps (If you set a different start page, go to aka.ms/office-install.)

Tip: The 64-bit version is installed by default unless Office detects you already have a 32-bit version of Office (or a stand-alone Office app such as Project or Visio) installed. In this case, the 32-bit version of Office will be installed instead.

To change from a 32-bit version to a 64-bit version or vice versa, you need to uninstall Office first (including any stand-alone Office apps you have such as Project of Visio). Once the uninstall is complete, sign in again to www.office.com and select Other install options, choose the language and version you want (64 or 32-bit), and then select Install. (See Install Visio or Install Project if you need to reinstall those stand-alone apps.)
