Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
A confirmation (activation) code for Office 2007 cannot be generated here.
To activate Office 2007, use the built‑in Activation Wizard with a valid 25‑character product key (format XXXXX-XXXXX-XXXXX-XXXXX-XXXXX):
- Start any Office 2007 program (for example, Word 2007).
- When prompted, enter the 25‑character product key from:
- The sticker on the CD case or other packaging, or
- The Certificate of Authenticity, or
- The confirmation email from an online purchase.
- After entering a valid product key, the Activation Wizard will offer:
- Activate over the Internet (recommended): it will contact Microsoft’s servers and, if the key is valid and not overused, activate automatically.
- Activate by telephone: use the phone numbers provided in the wizard or in this article to contact the Activation Center. Provide the installation ID shown on your screen; the agent will give a confirmation ID to type back into the wizard.
If the product key is lost, contact Microsoft support with valid proof of purchase. If the key does not work or has been blocked (for example, if it was resold or fraudulently obtained), contact the seller for a refund.
A confirmation ID can only be issued by Microsoft’s activation service (Internet or phone) after validating a genuine, unused product key; it cannot be created manually from the installation ID.
