Solution 1Recommended

Transfer a Retail Office License via Your Microsoft Account

Retail licenses of Office, such as a separately purchased Office 2013 key, can typically be transferred to a new computer using the associated Microsoft account.

A retail version of Office 2013 is transferable under its license terms. If you have previously redeemed your product key, the license is permanently linked to your Microsoft account. You do not need the original product key to reinstall; you only need to sign in and download the installer from your account dashboard.

1
Sign in to Microsoft

Go to the official Microsoft Account website and sign in with the email address and password associated with your Office purchase.

2
Navigate to Subscriptions

Click on the 'Services & subscriptions' tab located in the top navigation menu of your account dashboard.

3
Install Office

Locate your Office 2013 product in the list of services and click the 'Install' link to download the setup file to your new computer.

Activation on a Broken PC: Because your old laptop is damaged, you cannot manually uninstall Office to deactivate it. If online activation fails on the new computer, choose the 'Activate by telephone' option to contact Microsoft support and explain the hardware was destroyed.

Frequently Asked Questions

How do I know if my Office license is OEM or Retail?

OEM licenses typically come preinstalled on a new computer at the time of purchase and are tied to that specific hardware. Retail licenses are purchased separately, either online or in a physical store, and can usually be transferred to a new device.

Can I transfer Office 2013 without the 25-character product key?

Yes, if you previously linked the Office 2013 product key to your Microsoft account. You can simply log into your Microsoft account on the new computer, navigate to 'Services & subscriptions', and download the installer from there without needing to re-enter the product key.

What should I do if my original computer is broken and I cannot uninstall Office first?

If you own a retail license, you can still install Office on the new computer. If activation fails because the license registers as active on the broken PC, select the option to activate by telephone. The automated system or support agent will help you activate it after you confirm the original hardware is no longer in use.

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

No. Standard retail licenses for older standalone versions like Office 2013 only permit installation on one computer at a time. To install it on a second computer, it must first be uninstalled or deactivated from the first machine.
