1) Before you install
Check system requirements and prerequisites:
- Use a stable internet connection (some tests require it to load or submit).
- Make sure you have administrator rights to install software.
- Close other browsers and apps that could interfere with the exam environment.
- Confirm your school’s test instructions (some require a specific link or a specific launch method).
2) Download and install
Important: Always download LockDown Browser from the official source provided by your school/testing provider. Installing from unofficial sites can be unsafe and may cause failures.
- Download the Windows 11 installer.
- Run the installer as administrator (right-click the installer → Run as administrator).
- Complete the installation and restart if prompted.
3) Launching the exam correctly
Many proctored exams require you to start LockDown Browser in a specific way. Use the launch method your institution provides (for example, opening a test link that triggers LockDown Browser, or launching the app from the Start menu if instructed).
- Start LockDown Browser only when you are ready to begin the test.
- Do not switch tabs or open other applications during the exam.
- If the test page does not load, wait briefly and follow the on-screen proctor instructions.
4) Common Windows 11 troubleshooting
A) LockDown Browser won’t open
- Restart your PC and try again.
- Ensure Windows 11 is fully updated.
- Temporarily disable VPN/proxy tools and close background security tools that may block the browser.
- Check that you are using the correct version for your test.
B) Installation fails
- Run the installer as administrator.
- Verify you have enough disk space.
- Remove or update conflicting software if your institution has warned about it.
C) Exam won’t start or page won’t load
- Confirm you are using the correct test link or launch flow.
- Try a different network if allowed (some institutions restrict this).
- Clear browser cache only if your proctor instructions allow it (LockDown Browser behavior can differ from normal browsers).
5) Best practices during the test
- Keep your device plugged in if possible.
- Do not attempt to bypass restrictions (this can lead to test invalidation).
- If something breaks, stop and notify the proctor or follow the in-test help option.
6) If you tell me your situation, I can tailor the steps
If you share what exactly you mean by “lockdown browser” (installing it, launching it, or fixing an error) and the exact error message, I can provide a more targeted checklist.
