Install on a PC (Office for home)

Before you begin: Did you redeem your product key and associate Office with a Microsoft account?

Not every purchase of Office includes a key, but if this is a new copy of Office and you got a key sent to you electronically or it was included in your packaging, you need to redeem it first. (If you've already done this, go to Step 1: Sign in to My Office Account.)

1. Go to https://setup.office.com/ and follow the prompts to sign in (or create a new Microsoft account).

Tip: Your Microsoft account is the combination of an email address and password you use to sign in to services like Outlook.com, Hotmail.com, Xbox LIVE, OneDrive, or Windows Phone. If you use any of these services, you already have a Microsoft account. Use this same account when you sign in to Office, or create a new one.

To create a new Microsoft account, on the sign in page select No account? Create one! You can use a phone number, an email account you commonly use, or get a new @outlook.com email address.

For more information about Microsoft accounts, see Microsoft account help.

2. Enter your product key and follow the rest of the prompts to redeem your product.

Example of an Office product key:

XXXXX-XXXXX-XXXXX-XXXXX-XXXXX

Step 1: Sign in to My Office Account to begin installing Office

1. Go to My Office Account at www.office.com/myaccount. If you're not already signed in with the Microsoft account associated with your copy of Office do that now. If you're signed in with a different account, sign out of that and then sign in again with the correct Microsoft account.

Note: You must be signed in with this account to install or reinstall, and to manage your Office software.

If your sign in was unsuccessful try signing in again with the correct account, or see "This is the right place to install and re-install Office" for a list of options, including what to try if you can't remember your Microsoft account.

Screenshot of My Account sign in page where you enter the Microsoft account you use with Office

2. Select Install. (If you have an Office 365 subscription you'll need to select Install > and then on the next page, select Install.)

This will start the installation of the 32-bit version of Office on your PC using the language you selected when you redeemed the product.

- OR -

Screenshot of Install page on My Account

To install the 64-bit version or a different language, click the link Language, 32/64-bit, and other install options.

From the Language drop-down list, select the language you want.

Note: For more information about changing languages if you've already installed Office, see Choose or permanently change the language of your Office installation. If you'd like to install language packs for additional display, help, or proofing tools, see Language Accessory Pack for Office 2016.
From the Version drop-down list, select the version, such as Office - 64-bit. If you're not sure which version is right for you, see Choose between the 32-bit or 64-bit version of Office.

Important: If you already installed the 32-bit version of Office, you'll need to uninstall it before installing the 64-bit version, and vice versa. To uninstall Office, see Uninstall Office from a PC.
Select Install.

Office is installed now. Select Close

Step 3: Activate Office

1. Start using an Office application right away by opening any app such as Word or Excel.

In most cases, Office is activated once you start an application and after you click Accept agreeing to the License terms.

Accept the License Agreement terms by clicking Accept

2. Office might activate automatically. However, if you see the Microsoft Office Activation Wizard, follow the prompts to activate Office.
