Install Office 2021 Using an Administrator Account

By installing Office 2021 as a Windows administrator, the software becomes globally accessible to all other local Windows accounts on the same machine.

Microsoft Office 2021 is a one-time purchase license tied to the specific computer rather than a user subscription. Therefore, once installed system-wide on the PC, any user profile can launch and use the applications independently.

1
Log in as Administrator

Turn on the computer and sign into Windows using an account that possesses local administrator rights.

2
Install Office 2021

Run the Microsoft Office 2021 setup file and follow the on-screen prompts to complete the installation.

3
Verify Access

Log out of the administrator account and sign into a secondary Windows account. Open the Start menu and search for Word or Excel to confirm the application launches successfully.

Frequently Asked Questions

Do I need to buy multiple licenses for different users on the same computer?

No. For an Office 2021 one-time purchase, a single installation by an administrator allows all local user accounts on that specific computer to use the software without requiring additional licenses.

Does this sharing method work for Microsoft 365 subscriptions?

Microsoft 365 operates differently because it is a subscription tied to a specific Microsoft account. To share Microsoft 365 apps with other users on separate accounts, you typically need a Microsoft 365 Family subscription.

Why can't another user see the Office apps after I installed them?

If secondary users cannot find the applications, ensure you installed the software using an Administrator account. You may also need to manually pin the application shortcuts to their Start menu or desktop from the main program files folder.
