Question

What should I do if I receive the "Blocked Application Detected" error in Respondus LockDown Browser?

Environment

• GRCC Blackboard 
• Respondus LockDown Browser

Information

The "Blocked Application Detected" error occurs when the Respondus LockDown Browser identifies an application on your system that needs to be closed before an exam can begin. This is a security feature designed to maintain the integrity of the online examination environment.

Ensure that no unauthorized software is running during an exam. This includes virtual machines, screen capture, messaging apps, and more.

It’s recommended to restart your computer before starting an exam to clear any residual applications that might be running in the background.

Answer

1. Identify the Blocked Application:
   • Take note of the application name that Respondus is indicating as blocked.
   • Close the indicated application(s) manually by finding them in your taskbar or using Task Manager (Ctrl + Alt + Del).
2. Restart Respondus LockDown Browser:
   • After closing the blocked application(s), shut down the Respondus LockDown Browser completely.
   • Relaunch the browser and attempt to access the exam again.
3. Check for Background Processes:
   • Some applications run background processes that are not visible on the taskbar.
   • Use Task Manager to identify and close any background processes related to the blocked application.
4. Disable Startup Applications:
   • Prevent the issue from recurring by disabling startup applications from Task Manager > Startup tab.
   • Restart your computer to apply the changes.
5. Address Antivirus Software:
   • Temporarily disable or close any running antivirus software, as it may interfere with Respondus.
   • If the issue persists, especially with AVG Antivirus, uninstall the antivirus software as it may continue to block Respondus even when 'turned off'.
     • To uninstall, go to Control Panel > Programs and Features or Add or Remove Programs.
     • Find the antivirus program, select it, and choose Uninstall.
     • Follow the on-screen instructions to remove the software.
   • Remember to restart your computer and reinstall or reactivate your antivirus software after completing your exam.
6. Seek Further Assistance:
   • If the error persists, contact GRCC IT support for further assistance.
   • Be prepared to provide the name of the blocked application and any steps you have already taken to resolve the issue.
