Where your key is
Every paid order delivers the product key in two places:
- The order confirmation email — under the license key section.
- Your Lizensa dashboard — open Orders, select the order, and use Copy.
The generic activation flow
- Install the software first — official installer or ISO (see the install guides in this collection).
- Start the app or system and open the activation screen.
- Paste the 25-character key exactly as copied — when typing by hand, watch for 0/O and 1/I confusion.
- Confirm and wait for the "activated" confirmation.
Per-product shortcuts
- Windows 10 / Windows 11 — Settings → System → Activation → Change product key (see the Windows 10 and Windows 11 install guides).
- Office retail (2019/2021/2024) — redeem at office.com/setup first; the key is then bound to your Microsoft account.
- Office LTSC / volume — activate in the Office wizard or with
ospp.vbs(see the ODT guide). - Office for Mac — redeem at office.com/setup, then sign in on the Mac.
- Antivirus and other vendors — use the vendor activation portal named in your order email (Norton, Bitdefender, Kaspersky, and others each have their own).
If activation fails
Check that the edition matches the key, then follow the troubleshooting checklist.
