Problem

When running a Charlotte task that uses internet explorer as the browser, it fails with the exception "org.openqa.selenium.remote.SessionNotFoundException: Unexpected error launching Internet Explorer. Protected Mode settings are not the same for all zones. Enable Protected Mode must be set to the same value (enabled or disabled) for all zones. (WARNING: The server did not provide any stacktrace information)"

Solution

Set the "Enable Protected Mode" to the same value for all zones

  1. Navigate to "Tools > Internet Options"
  2. Click on the "Security" tab
  3. Make sure that each of the four zones (Internet, Local intranet, Trusted sites, Restricted sites) are all the same value
