To install or reinstall Office 365, Office 2016, or Office 2013, or to manage your Office 365 subscription, you must use the Microsoft account you associated with one of those versions.
If you signed in to My Account, or to office.com and then clicked the Install Office button, you'll see a message that says, "This is the right place to install and re-install Office 2016, Office 2013, and Office 365, or manage your Office 365 subscription, but you signed in with an account not associated with any Office products."
To continue with installing the desktop version of Office, or to manage your subscription select from below.
To install or reinstall Office, or to view or manage your Office 365 subscription at My Account, you must be signed in with the Microsoft account that’s associated with your personal copy of Office.
Enter your product key to see a portion of your Microsoft account.
If your copy of Office came with a 25-character product redemption key like in the image below or on an email receipt, (whether or not you have a key depends how you got your copy of Office), try the following using your key:
Go to www.office.com/setup. Enter a Microsoft account or follow the prompts to create a new one.
After signing in, type the 25-character key that came with your copy of Office.
On the My Office Account page, you'll see a portion of the Microsoft account you used to buy or activate Office, or that you used when you first signed in to My Account.
Select the link Sign in with your other Microsoft account, and then sign in with the correct Microsoft account.
If this isn't enough to remember your Microsoft account, you don't have or never received a product key, or someone installed Office on your behalf with a different email address and password, contact support by selecting the Ask support (it's free) link on the My Office Account page to review your options.
Check the email address signed in with. For example, if it’s the email address you use with work or school, you should sign out and then sign in with the Microsoft account email address that’s associated with your personal copy of Office instead.
To sign out, select Sign out at the top of the page.
If in fact you wanted to sign in to Office with your work or school account, just sign out of the account you're currently signed in with, and sign in again with the correct account at office.com.
If you're certain you signed in with the correct Microsoft account, contact support by selecting the Ask Support link on the My Office Account page to review your options.
If you bought or received a copy of Office, but haven't installed it yet, it's possible you missed the step to associate Office with a Microsoft account.
If a product key came with your copy of Office, go to office.com/setup and follow the steps on screen to add or create a new account, and then enter your product key. See Where to enter your Office product key for more details.
If you don't have an Office 365 subscription, or own a copy of Office 2016 or Office 2013, you can buy or try Office now.
