Select the steps for your Office product

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

Shows an example of an Office product key

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.

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 -

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

  1. 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.

  2. 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.

  3. Select Install.

  1. Sign in with your work or school account at https://aka.ms/office-install.

    Notes: 

    If you don't see Office listed, your plan probably doesn't include Office applications. If you know your plan includes Office, you may not have a license assigned, see What Office 365 product or license do I have? If Office is not listed ask your Office 365 administrator to assign a license to you.

  2. Select a Language, and accept the default to install 32-bit, or select Advanced and choose 64-bit from the drop-down list. If you’re not sure which version to install, see Choose the 64-bit or 32-bit version of Office 2016.

    Important: If you currently have the 32-bit version of Office installed on your PC, you'll need to uninstall that version before you can proceed with installing the 64-bit version and vice versa.

Sign in or installation help FAQ

The following are a few of the more common questions or issues when trying to install Office. For additional issues and their possible solutions, also see Troubleshoot installing Office 365 and Office 2016.

Account questions:

Before you can install Office 365 or Office 2016, 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 step-by-step tabs above to help you with the rest of the install process.

Screenshot of Install page on My Account

If the Microsoft account or work or school account isn't working, see I forgot the username or password for the account I use with Office.

If there's no option to install the desktop applications your admin may not have assigned a license to you. Find out if you have a license to install Office.

If you're a student or teacher and your institution didn't give you a license, find out if you're eligible to Get Office 365 for free.

If you're trying to sign in with your work or school account to www.office.com and your sign in is blocked, it likely means your Office 365 administrator set up a security policy that's preventing you from signing in to that location. To install Office, try signing in at aka.ms/office-install instead. Follow the remaining steps in the "Office for business step-by-step" section on the PC step-by-step tab to finish installing Office.

Notes: 

If you're still not able to sign in, contact your administrator.

Purchase and product key questions:

Not all versions of Office 365 or Office 2016 include a key, but if yours did, you need to redeem it before you can install Office. Go to office.com/setup and sign in with an existing Microsoft account or create a new one, then enter your product key. Follow the remaining prompts to finish linking your Microsoft account with this version of Office.

No product key or not sure if you need one? See Using product keys with Office 365, Office 2016, or Office 2013.

The steps in this topic assume you have Office 365 or Office 2016 and you're ready to install or reinstall it. Don't have the latest version yet?

Install questions or errors during install

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.

If you bought a stand-alone version of an Office app, for example Visio 2016 or Word 2016, in most cases you install this app in the same way you install the Office suite, by signing in to www.office.com with your Microsoft account, or work or school account and selecting Install for your stand-alone product.

If you have a subscription to Project Online Professional, Project Online Premium, or Visio Pro for Office 365, see Install Project, or Install Visio for the steps to install the apps that are part of those subscriptions.

If Office seems to be taking a very long time to install, this may be caused by problems with your internet connection, firewall, or anti-virus software. For possible solutions, see Office is taking long to install.

Office can also take long to install because of slow internet connections (such as a dial-up connection). If you don't have good connection, install Office using the Use the Office 2016 offline installer.

Office won't install: Your computer must be running a supported operating system to install Office. You can find a list of which systems are supported on the system requirements page. For example, your install won't be successful if you're trying to install Office on a computer running Windows Vista or Windows XP operating system, or on a Chromebook. If your computer can't install the full desktop version of Office, try the free Office Online apps using your desktop browser.

I received an error message: If you got an error message while trying to install Office and it has a Learn More link, select it to get information for how to troubleshoot that particular error. If there wasn't a link, see Troubleshoot installing Office 365 and Office 2016.

Help with specific applications, and help for Office 365 admins:

If Office is installed, but you need help with Office basics, or learn how to do a specific task such as print a document, set up an account in Outlook, or use VLOOKUP in Excel, go to the top of this page and select Apps or Learn Office.

You can also type what you're looking for using the search bar in the upper-right corner.

If you're the Office 365 admin of an Office for business plan, users in your organization can only install Office using the steps in this topic as long as your plan includes the desktop version of Office, and you've assigned the user a license and given them permission to install Office (Manage user software in Office 365).

For information about how to assign licenses, see Assign licenses to users in Office 365 for business.

If you've run out of licenses and need to purchase more, see Buy licenses for your Office 365 for business subscription.
