Check your Browser

  • Make sure you are using Chrome or Firefox. Safari and Edge will not work.
  • Clear your browser cache (instructions can be found here)

Check your URL

Check your Browser Extensions

  • Extensions designed to prevent pop-ups, scripting, or ads may interfere with launching Respondus and should be disabled

Uninstall and Reinstall Lockdown Browser

If you are still having issues, feel free to contact the IT Service Desk at (309) 677-2964.


If you run the Respondus Lockdown desktop app instead of through a browser, review the following:

Check your Application

For Mac:

  • Go to your Applications folder in Finder.
  • Look for Lockdown Browser.
  • Open the application.
For Windows:
  • If the application is downloaded onto your desktop, look for a Lockdown Browser icon with a shortcut arrow. 
  • If not, use the installer application to re-install Lockdown Browser to a location you can remember.

Close Interfering Applications

Respondus may display an error message saying it cannot run until a particular application is closed. Select "Close Application" to let Respondus automatically close whatever is interfering. After that, it should bring you to Canvas.
