Step By Step Setup

Use these step-by-step instructions to help you install or reinstall Office 365 or Office 2016 on a PC, laptop, or 2-in-1 computer. The steps include information about how to install Office in a different language, or how to install the 64-bit version.

The steps below differ if your Office product is part of an Office for home or Office for business plan, so select the correct steps for your product.

Select the steps for your 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 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,, 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 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:

    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.
