Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Reinstall Office 2013 from the Microsoft account originally used to activate it; a previously redeemed product key normally does not need to be entered again.
Reinstall from your Microsoft account
- Open Microsoft account Services & subscriptions.
- Sign in with the Microsoft account used when Office 2013 was first activated.
- Locate Office 2013, then select Install.
- Run the downloaded installer.
- Open Word or Excel and follow the activation prompts. If prompted to sign in, use the same Microsoft account.
The Office licence should have been associated with that account during its original activation, allowing reinstallation without a CD or re-entering the key.^1^
If Office 2013 is not listed
- Try any other Microsoft account that may have been used when the key was first redeemed.
- If this is a new, unused retail key, redeem it at https://microsoft365.com/setup, sign in, enter the key, and follow the prompts.^2^
- If the key came from an employer, volume-licensing agreement, or business-managed installation, contact the organization’s IT administrator. Those editions may use a different installer and activation method.
- Do not download a random Office image until you know the exact edition printed on the key card or purchase receipt—for example, Home and Business 2013, Professional 2013, or Professional Plus 2013. Installation media must match the licensed edition. A Microsoft Q&A answer provides offline media specifically for Office 2013 Professional Retail, but that should be used only if that is your exact edition.^3^
Office 2013 reached end of support on April 11, 2023 and no longer receives security updates, bug fixes, or technical support. Consider moving to a supported Office release, especially on a business computer.^4^
