Solution 1Recommended

Reinstall Office via Your Microsoft Account

Use your linked Microsoft account to download and activate the Office suite on your new or reset device.

A one-time Office license (such as Office Home & Student) is permanently linked to your Microsoft account once redeemed. You do not need the original product key to reinstall it.

Uninstall from the old device (if possible)

If you still have access to your old laptop, open the Control Panel, navigate to Programs and Features, and uninstall Microsoft Office to free up the license.

Sign in to Microsoft Services

On your new or reset laptop, open a web browser and go to https://account.microsoft.com/services or https://www.office.com. Log in using the exact Microsoft account associated with your Office purchase.

Download the installer

Locate your Office product under the 'Services & subscriptions' section and click the 'Install' button to download the setup file.

Install and activate

Run the downloaded setup file. Once the installation completes, open any Office application like Word and follow the prompts to sign in and activate your license.

Reinstall Office via Your Microsoft Account

Device Limit Considerations: If your old device is broken or unavailable, you can still install Office on the new one. However, if you encounter an activation error stating the limit is reached, you may need to select the 'Activate by phone' option to complete the transfer.

Frequently Asked Questions

Do I need my original product key to reinstall Office?

No, your product key is only used once during the initial setup. After that, your license is digitally linked to your Microsoft account, which you use for all future installations.

How do I find which Microsoft account is linked to my Office purchase?

Check your email inboxes for purchase receipts from Microsoft. You can also try logging into account.microsoft.com/services with any email address you might have used to see if the Office license is listed.

What if I get an 'activation limit reached' error?

One-time purchases are typically limited to one device. If you couldn't uninstall Office from the old laptop, you may receive this error. You can usually resolve it by choosing the option to activate by phone and following the automated prompts to verify the device transfer.
