- Product
- Microsoft Office Home and Student 2013
- Device & OS
- not provided
- Scenario
- Reinstalling or migrating Office 2013 to a new computer after the initial product key has already been redeemed.
- Observed behavior
- The user is unable to use the original product key printed on the card to reinstall the software, as the license is now linked to their Microsoft account with a different partial key.
Ensure you have the login credentials for the Microsoft account originally used to redeem your Office 2013 product key, and completely uninstall Office from your old computer if migrating to a new one.
Reinstall Office 2013 via Microsoft Services and Subscriptions
Use this method to download and reinstall Office 2013 directly from your Microsoft account without needing to re-enter the original product key.
It is completely normal for the product key printed on your retail card to differ from the partial key shown in your Microsoft account. The card key is a one-time redemption code used to permanently link the software license to your account.
Because Office Home and Student 2013 is licensed for a single computer, you must uninstall it from your previous machine before activating it on a new one to avoid activation errors.
If you are moving Office to a new PC, open the Control Panel on the old computer, select 'Programs and Features', locate Microsoft Office 2013, and click 'Uninstall'.
On your new or current computer, open a web browser and navigate to https://account.microsoft.com/services. Sign in with the exact Microsoft account that was originally used to redeem your Office 2013 key.
Scroll through your list of services and subscriptions until you find 'Office Home and Student 2013'.
Click the 'Install' button next to your Office 2013 product. Follow the on-screen prompts to download the setup file and complete the installation process.

Frequently Asked Questions
Why doesn't my Office 2013 product key match the one in my Microsoft account?
The product key on the physical card is a one-time redemption code used to bind the software to your account. The partial key shown in your Microsoft account is the actual installation key generated after redemption, which is why the two do not match.
Do I need to enter my product key again to reinstall Office 2013?
No, once your product key is redeemed and linked to your Microsoft account, you do not need to enter it again. Simply log into the Microsoft Services and Subscriptions page to download and reinstall the software.
Can I install Office Home and Student 2013 on a second computer?
Office Home and Student 2013 is a 1-PC license, meaning it can only be active on one computer at a time. To move it to a new computer, you must first uninstall it from the old one before downloading and activating it on the new device.
