Step 1: Download Office
Download the office via www.setup.office.com
Step 2: Open the Activation Wizard
After installation, open Word (or any Office app) — when the Office Activation Wizard appears, select "Activate by phone"
The wizard will display your Installation ID (IID) — shown as 9 groups of 7 digits — write it down or copy it
Step 3: Select Your Country
In the activation wizard, select your country/region from the dropdown — the Microsoft Activation Center phone number will appear
Step 4: Get Your Confirmation ID
You have two options:
Option A — By Phone:
Call the number shown, press 1 to agree with the recording, then press 3 for Office activation, then press 1 and enter the Installation ID numbers when prompted
When asked how many computers the key is installed on, answer "zero"
The automated system will provide a Confirmation ID (CID)
Option B — Online (faster):
