Why can't I install Microsoft 365 or Office?

: If someone has shared their Microsoft 365 Family subscription with you, you won't see an install button and the "Start using Microsoft 365 apps" link won't work until the person who invited you completes the sharing. Learn more.

If you signed in to www.office.com and selected the Install button, you may get a message to Go premium instead of a prompt to begin the installation.

Why am I getting this message? You'll see this because you signed in to office.com with your Microsoft account (shown in the upper right corner), but this isn't recognized as the same account you associated with Microsoft 365 or a non-subscription version of Office such as Office Home & Business (or a stand-alone app such as Project Standard or Project Professional).

You won't be able to install the desktop apps like Word, Excel, or PowerPoint until you first redeem your product key (if you received one) and then use that same account to sign in to office.com. You only need to redeem your product key once to associate it with your Microsoft account. See below for more info.

Message to Go premium after selecting the Install Office button

If you recently bought Microsoft 365 or Office, someone shared Microsoft 365 with you, or you got it through work, it's possible you're seeing the message Go premium because you haven't associated the product with your Microsoft account. See the section: How you got Microsoft 365 or Office

For other issues, select from the following:

You can't remember which Microsoft account you associated with Microsoft 365 or Office

See I forgot the username or password for the account I use with Microsoft 365 or Office.

You signed in with the wrong account and need to sign out

Check which email address you signed in with by looking in the upper right corner of the window. For example, it's possible you're signed in with a personal Microsoft account instead of your work or school account and the version of Microsoft 365 or Office you're trying to install was provided through your work or school.

Sign out and then sign in with your work or school account. Or, if you're trying to install a home version of Microsoft 365 or Office, sign out and then sign in with the correct Microsoft account.

From the upper right corner, select the name you signed in with and then select Sign out.
Sign in again using the correct account at office.com.

If you're certain you signed in with the correct account, contact support by selecting Contact Us at the bottom of this page.

You don't own Microsoft 365 or a non-subscription version of Office (or a stand-alone app such as Project Standard)

To install the desktop Office apps from office.com, you need a Microsoft 365 subscription, or a non-subscription version such as Office Home & Business or Office Home & Student.

If you don't have one of these versions of Office, you can buy Office now or start a one month free trial of Microsoft 365.
