Download and install or reinstall Office 365 or Office 2016 on your PC or Mac

Before installing Office: Make sure your computer meets the system requirements. For example, Office can't be installed on Chromebooks, or computers running Windows Vista or Windows XP.

Basic install steps

How you install or reinstall Office 365 or Office 2016 (or a single, stand-alone application such as Access 2016 or Project 2016), depends on whether your Office product is part of an Office for home or Office for business plan. If you're not sure what you have, see what Office products are included in each plan and then follow the steps for your product.

Need more detailed steps or you want to install the 64-bit version of Office? Follow the Step-by-step installation instructions below, instead of these basic steps.

Step-by-step installation instructions

The drop-down list below contains detailed install steps along with screen captures that show how to download and install Office on either a PC (laptop, desktop, or 2-in-1), or a Mac. The steps also include install options such as how to select a different language or how to install the 64-bit version of Office.

If you're not sure your product is part of an Office for home or Office for business plan, see what Office products are included in each plan and then select from below.

If this is a new copy of Office and you haven't redeemed your product key (if one came with your copy) or associated it with a Microsoft account, go to office.com/setup and follow the prompts to sign in and enter your product key.

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.

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.

    Screenshot of Microsoft account sign in page

    Tip: 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.

  2. If you have an Office 365 you'll need to select Install > first.

    To begin the process of installing the 32-bit version of Office on your PC using the language you selected when you redeemed the product, select Install.

    OR

    To install the 64-bit version or a different language instead, expand the sections below and follow the steps to install those versions. If you're not sure about the differences between 32 and 64-bit and which is best for you, see Choose the 32-bit or 64-bit version of Office.

Note: When installing Office 2016 you might see a message that says, “Stop, you should wait to install Office 2016”. This means Office detected a compatibility issue with something else installed on your computer. Select the Learn why link in the error message.

Other options: install the 64-bit version or a different language:

Important: If you currently have the 32-bit version of Office (or a single, stand-alone Office app such as Visio) installed on your PC, you'll need to uninstall that version before you can proceed with installing the 64-bit version.

  1. Select the Language and install options link.

    Screenshot of Install button and link for selecting other language and install options
  2. On the Language and install options page, select the link, Additional install options.

  3. In the Other versions of Office section, select Office - 64-bit from the drop-down list, then select Install. Follow the remaining steps in the section below, Install and activate Office.

    Screenshot of drop-down list to select the option to install Office - 64-bit

You can change the language of Office by choosing a different language then the one you selected when you redeemed Office.

Note: This option is only available if you have a subscription to Office 365 Home, Personal, or University, or a one-time purchase of Office 2016. It doesn't apply to one-time purchases of Office 2013 such as Office Home and Student 2013.

  1. Under Install Information, select the Language and install options link.

    Shows the Language and install options link in Office 365 account management

  2. In the drop-down list box next to Language, choose the language you want to install.

    Shows the language choices in Office 365 Home

  3. When you've made your selection, select Install. Follow the remaining steps in the section below, Install and activate Office.

    Shows the Install language screen in Office 365 account management

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.

Step 2: Install and activate Office

After selecting Install in the steps above, Office performs a series of pre-checks. Once that's complete, begin the installation by going to to the install pop up that appears on your computer:

  1. Depending on your browser click Run (in Internet Explorer), Setup (in Chrome), or Save File (in Firefox). If you're using Edge as your browser, first click Save, and then click Run.

    Screenshot of browser options: in Internet Explorer click Run, in Chrome click Setup, in Firefox click Save File

    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.

    Office is installed now. Select Close
  3. 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
  4. 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.

Troubleshooting

Expand a section below for troubleshooting help. If you don't see your issue listed, try Troubleshoot installing Office 2016 or Office 2013

If Office seems to be taking a very long time to install, there could be a problem with your internet connection. For possible solutions, see Why is Office taking so long to install? You may also want to try installing Office using the Office 2016 offline installer.

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 the problem. If there wasn't a link, see Troubleshoot installing Office 2016 or Office 2013.

If your Install button is grayed out, see Install button doesn't install Office.

    Note: If you're unable to sign in you may be signing in to the wrong Office 365 service, see Where to sign in to Office 365.

    If you don't see Office listed, your plan probably doesn't include Office applications.

If Office is not listed ask your Office 365 administrator to assign a license to you.

    Important: The process that installs Office 2016 also uninstalls all Office 2013 products. See "Stop, you should wait to install Office 2016" error or How do I reinstall Office 2013 after an Office 2016 upgrade.

  3. 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 (or a single, stand-alone Office app such as Visio) installed on your PC, you'll need to uninstall that version before you can proceed with installing the 64-bit version.
