Before you begin: Did you redeem your product key and link 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 or your online order, you need to sign in with an existing Microsoft account or create a new one and then redeem your key. Watch the video, Redeem your product key.

If you've already done this step, go ahead to the next section 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).

    A 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 and can use this account when prompted to sign in, or you can 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 already commonly use, or create a new @outlook.com email address.

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

  2. Enter your product key and follow the rest of the prompts to complete the redemption process.

    Example of an Office product key:

    XXXXX-XXXXX-XXXXX-XXXXX-XXXXX

    Shows an example of an Office product key

After completing this step, your Microsoft account will be associated with this version of Office. Why you need a Microsoft account with an Office for home version of Office.

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

  1. Go to My Office Account at www.office.com/myaccount and 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 and don't see an option to install Office, sign out and then sign in again with the correct Microsoft account.

    Screenshot of the Microsoft account Sign In page

    Note: You must be signed in with your Microsoft account to install or reinstall, and to manage your Office software. Why you need a Microsoft Account with Office for home

    For help with your account, see I forgot the username or password for the account I use with Office, or try "This is the right place to install and re-install Office".

  2. You have the choice to install the 32-bit or 64-bit version of Office. 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 this is a reinstall or an upgrade to a newer version of Office and you previously installed the 32-bit version of Office, you'll need to uninstall it before installing the 64-bit version, or vice versa. If you don't uninstall the other bit-version first, you'll get an error message during the installation. To uninstall Office, see Uninstall Office from a PC. Bookmark this page so you can come back here quickly and complete the installation for the version you want to install.

    Install the 32-bit version

    Select Install. (If you have an Office 365 subscription select Install > and on the next page, select Install.) By default this installs the language you selected when you redeemed the product.

    Screenshot of Install page on My Account

    Install the 64-bit version

    Click the link Language, 32/64-bit, and other install options.

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

  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, or the 32-bit version of a stand-alone app such as Project or Visio, you'll need to uninstall that version before you can proceed with installing the 64-bit version and vice versa.

Sign in or installation FAQ

The following are a few of the more common questions or issues when trying to install Office.

Tip: Don't see your issue listed? Try Troubleshoot installing Office 365 and Office 2016 for additional issues and their possible solutions.

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.

After signing in with your work or school account you don't see an option to install the desktop applications on the Office 365 home page, go to aka.ms/office-install instead, and then follow the remaining steps in the "Office for business step-by-step" section on the PC step-by-step tab to finish your installation.

If you still don't see an option to install Office at aka.ms/office-install, it's possible your admin hasn't 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.

Product key, purchase, and installing older versions of Office:

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?

Installation help for older versions of Office:

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.

When installing Office on a PC, you must be an administrator on the PC computer where you want to install Office 365, Office 2016, or Office 2013. If you're not sure, see Check if you have local admin rights to install Office .

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.

The Office apps are available to install on your iPhone and iPad, Android device, or Windows phone and tablet. See Set up Office apps and email on a mobile device.

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.
