Install or reinstall Office from My Office Account

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 and follow the prompts to sign in and enter your product key.

Begin installing Office
  1. Sign in to My Office Account at with your Microsoft account. This is the email address and password you associated with your copy of Office.

    Sign in to Office with a Microsoft account email address and password

    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. Select Install and depending on your product, select Install again. By default, this installs the 32-bit version of Office on your PC using the language you selected when you redeemed the product. If you want to install the 64-bit version, change your language, or install Office 2013 instead, see the section Custom install options.

    Select Install

    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, or see the Troubleshooting section below.

  3. Depending on your browser, go to the install pop up that appears and click Run (in Internet Explorer), Setup (in Chrome), or Save File (in Firefox).

    Browser options: in Internet Explorer click Run, in Chrome click Setup, in Firefox click Save File

    The install begins.

  4. 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
  5. 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 agree to the License terms by clicking Accept.

    Accept the License Agreement terms by clicking Accept
  6. Office might activate automatically. If you see the Microsoft Office Activation Wizard, follow the prompts to activate Office. If you need help, see Activate Office 365, Office 2016, or Office 2013.
