Install Office on a New Computer with Microsoft 365

Microsoft 365 allows you to install Office on multiple devices simultaneously without manually disabling previous installations.

If you have an active Microsoft 365 subscription, installing Office on a new computer is straightforward and will not immediately disable the software on your old computer.

Sign in to Microsoft

Open a web browser on your new computer, navigate to office.com, and sign in with the Microsoft account associated with your subscription.

Download the installer

Click the 'Install Office' or 'Install apps' button located in the top right corner of the homepage to download the setup file.

Install and activate

Run the downloaded setup file. Once the installation is complete, open any Office app (like Word) and sign in to activate. Your old computer will remain active.

Device Limits: You can be signed in to Microsoft 365 on up to 5 devices at the same time. If you exceed this, Microsoft will automatically sign you out of the least recently used device.

Transfer a One-Time Purchase Office License

For standalone versions of Office (like Office 2019 or 2021), you may need to manage the license transfer manually to use it on a new computer.

Frequently Asked Questions

Will my files be deleted if I uninstall Office from my old computer?

No. Uninstalling Microsoft Office only removes the application software. Your personal documents, spreadsheets, and presentations will remain safely stored on your computer's hard drive.

How do I check which type of Microsoft Office license I have?

Open any Office application such as Word, click on 'File', and select 'Account' from the bottom left menu. Under 'Product Information', you will see whether you have a subscription product (Microsoft 365) or a one-time purchase (e.g., Office 2021).

Can I use the same Microsoft Office product key on two computers at once?

If you have a one-time purchase license, the product key is strictly limited to one computer at a time. If you have a Microsoft 365 Family or Personal subscription, your account handles the licensing, allowing you to use Office on multiple active devices simultaneously.
