# Why is TSB not launching in Windows?

If clicking on the Talview Secure Browser (TSB) doesn’t open anything on Windows, it may be due to installation issues, blocked permissions, or background apps. This can prevent you from starting your test.

| TSB didn’t install correctly          | Uninstall TSB completely, then [download and reinstall the latest version](https://www.talview.com/download-center).                                               |
| App is blocked by antivirus           | Open your antivirus and [**add TSB as a trusted app**](https://talview.freshdesk.com/support/solutions/articles/11000129091-secure-browser-troubleshooting-guide). |
| You don’t have permission to run apps | Right-click the `TSB icon → Run as Administrator.`                                                                                                                 |
| Background apps are interfering       | Close apps like screen recorders, VPNs, remote desktops, or pop-up blockers.                                                                                       |
| System is still *booting* or lagging  | Restart your computer and wait 1–2 minutes before trying again.                                                                                                    |

<Tip>
  ### Additional Tips:

  * Try launching TSB from the **Desktop icon** or **Start Menu**
  * Make sure the **installation file** was **actually run** after downloading
  * Confirm your antivirus/firewall is not silently blocking the app
</Tip>

## 🌐 Final Check: Confirm It’s Working

Before reattempting the test:

* Right-click the TSB icon and choose **Run as Administrator**
* Wait up to 10–15 seconds on slower systems
* Allow any pop-ups or permission requests
