Install on a PC (Office for home)
Tip: For Office 365 Home subscribers only: You can install Office on up to 5 PCs or Macs. Share your other four installs with friends or family, or use the same Microsoft account to install Office on your other computers. The steps to install are the same.
For a one-time purchase of Office 2016 such as Office Home & Student, Office Home & Business, or Office Professional: You can install Office on only one computer. However, you may transfer Office 2016 to another computer that belongs to you if you experience a hardware failure or you buy a new computer. For more information, see the Microsoft License Terms for your product, or see this blog post, Office now transferable.
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 I forgot the username or password for the account I 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 -
-
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.
-
Step 2: Install Office
1. Depending on your browser, click Save (in Edge), Run (in Internet Explorer), Setup (in Chrome), or Save File (in Firefox).
If you see the User Account Control prompt that says, Do you want to allow this app to make changes to your device? Click Yes.
The install begins.
2. 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.
Follow the instructions in the window, for example Click Start > All Apps to see where your apps are, and 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.
2. Office might activate automatically. However, if you see the Microsoft Office Activation Wizard, follow the prompts to activate Office.
If you need activation help, see Activate Office 365, Office 2016, or Office 2013.
