How to Reuse an Office Product Key After Installation Fails
Question details
The user wants to know if a one-time Office product key can be reused on another computer or retried after the initial installation process fails.
- Product
- Microsoft Office
- Device & OS
- not provided
- Scenario
- Attempting to reinstall or complete a Microsoft Office installation after an initial setup failure.
- Observed behavior
- The installation failed, leaving uncertainty about whether the product key was consumed and linked to the Microsoft account or if it can still be used.
Ensure you have the login credentials for the Microsoft account you originally used when attempting to redeem the product key, as the key may already be permanently linked to it.
Download and Install Office Directly from Your Microsoft Account
If the key was successfully redeemed before the installation failed, you no longer need the key. You can install Office directly from your connected Microsoft account.
Once a product key is entered, it associates the Office license with your Microsoft account almost immediately. Therefore, a subsequent installation failure does not invalidate your purchase.
Open your web browser and navigate to account.microsoft.com/services or Office.com/setup.
Log in using the exact Microsoft account credentials you used during the initial product key activation attempt.
Check the 'Services & subscriptions' section to find your purchased Office product.
Click the 'Install' button next to your Office product to download the installer and complete the setup on your computer.
Contact Microsoft Support for Key Verification
Use this method if your product key was not redeemed to your account, but you are still getting an 'already used' error when trying to reuse it.

Frequently Asked Questions
Can I use my Office product key on a different computer if the first install failed?
If it is a one-time purchase key (like Office Home & Student), it can only be active on one computer. However, if the first installation failed and the key successfully linked to your Microsoft account, you can simply log into that same Microsoft account on the new computer to install it without needing to type the key again.
Why does my Office key say it has already been used?
This typically means the product key has successfully been linked to a Microsoft account during your first attempt. You no longer need to enter the key; simply sign in to account.microsoft.com/services with that account to download and install Office.
How do I find out which Microsoft account my product key is linked to?
Microsoft does not provide a direct lookup tool for security reasons. You will need to try logging into account.microsoft.com with any email addresses you might have used during the activation process and check the 'Services & subscriptions' tab to see if the Office product appears.
