Bring the Hidden Dialog to the Front

2. If you find it, click Yes to proceed.
Close Conflicting Software
- LockDown Browser refuses to continue if other applications are open that could interfere. Before starting:
1. Close all other programs — browsers, Zoom, Discord, Spotify, etc.
2. Exit or disable background tools like:
  - Screen recorders or capture tools (OBS, Xbox Game Bar)
  - Chat or overlay apps (Teams, Slack, Steam overlay)
  - Antivirus pop-ups or update prompts
3. Restart your computer and try launching LockDown Browser again.
Run as Administrator (Windows)
1. Right-click the LockDown Browser shortcut → Run as administrator.
- This ensures it can present and confirm the “Self-Lock” dialog properly.
Allow the Dialog Through Windows Settings
- Sometimes the User Account Control (UAC) or Windows focus settings block system dialogs:
1. Go to Control Panel → User Accounts → Change User Account Control settings.
2. Make sure the slider isn’t set to “Never notify.”
3. Restart and try again.
