Step 5: Activate
- Office will try to activate online automatically.
- If you see an error (e.g., “used too many times”), choose Activate by telephone and follow the prompts.
- Optionally, ask for a secure link (e.g.
https://visualsupport.microsoft.com/xxxxxx) to enter your Installation ID and get a Confirmation ID faster.
After activation, restart Word and check under File → Account to confirm the new license is applied.
