If you open your Trend Micro program and see Not Yet Activated, it means the program hasn’t completed activation. This guide covers possible causes, quick fixes, and what to do if the issue doesn’t go away.
Not Yet Activated
Common Reasons
- Your program hasn’t been registered to your Trend Micro account.
- Your PC isn’t connected to the Internet or a firewall is blocking activation.
- You entered a retail activation code but the program is still asking for payment info.
- Your subscription renewed but the product hasn’t updated the activation status.
- Another security software is interfering.
- The activation server can’t be reached because of network settings.
Quick Troubleshooting Table
| Issue | What to Try | If Still Fails |
|---|---|---|
| Internet connection problem | Make sure you can browse any website before activating. Disable VPN temporarily. | Contact your ISP. |
| Retail activation code entered but program asks for payment info |
This is not charging you again — it’s asking to register a payment method for auto‑renew. This ensures your protection continues without interruption when your subscription ends. You may enter your card details to enable auto‑renew. |
If you prefer to renew manually, you can turn off auto‑renew anytime via your Trend Micro Account |
| Activation code not accepted | Check for typos (1 vs I, 0 vs O). Confirm code matches product version. | Contact Support to check if your code is correct. |
| Other antivirus blocking activation | Uninstall or disable conflicting antivirus then activate. | Update Trend Micro after removing the other software. |
| Multiple device confusion | Sign in with the same Trend Micro account on all devices. | Follow the steps to install and activate Trend Micro on another device |
