Respondus - students

Downloading Respondus and accessing the exam

Can I install the software on more than one computer?

Yes, you can install Respondus on multiple computers.

Can I access the exam even if I am not registered in Esse3?

No, you can not. You must have registered for the exam on Esse3. 

I launched Respondus, but I can not access the exam. Why?

The software has to be launched from the exam page. You must follow this order:

  • access the exam page on with a normal browser
  • select the quiz (click on the checkbox icon)
  • the quiz will ask you to launch Respondus LockDown Browser by clicking on a blue button.
During the exam I get the following error message: "A mandatory parameter (cmid) is missing".

The problem may be caused by an interference from antivirus/antimalware software or firewall. Try to temporarily deactivate or uninstall them during the exam. If this does not solve the problem, it may be a blockage by the Internet connection router: try connecting to a different network, e.g. by hotspotting your mobile phone. At each new attempt, close the browser and repeat the procedure.

Can I leave the test page?

You can not leave the test page until you have answered all the questions and definitively submitted the answers.

The exam I must take is made up of two parts (two quizzes). Once the first part (first quiz) is finished, I cannot access the second part (second quiz). Why?

Take the first quiz and submit the answers. Then close Respondus and, with your normal browser (without Respondus), return to the course home page. Here, select the second part of the exam and access the quiz with Respondus.

Does the software block only the applications I can see (i.e. those with a graphical interface) or even those in the background?

The system blocks all applications, even those in the background (such as Skype), which could allow you to violate the security and the integrity of the exam.

Could the software cause other applications to crash by forcing them to close or to overwrite data not related to Respondus?

When you launch Respondus LockDown Browser, it is reported the name of the applications that will be closed; for each application, you are prompted for confirmation before closing them. When in doubt, you can refuse to give consent, close LockDown Browser and return to your desktop, so that you can manually close the reported applications.
Our advice is to close all the other applications before launching Respondus, especially if you have unsaved documents open.

Does Respondus somehow stay active in the background when not in use and send data to some server?

Once Respondus is closed, all monitoring and control operations are terminated, and the system does not remain active in the background.

Does Respondus leave traces once uninstalled or is it completely removed?

The program and all its files are completely removed.

I am prevented from accessing or LockDown Browser closes every time I try to launch it. Why?

We have found an incompatibility with Bit Defender antivirus software. If it is installed on your PC, we recommend disabling it before taking an online exam; you can reactivate it after the exam has ended.

Respondus - Devices and operating systems

Is Respondus compatible with Linux?

Respondus is not compatible with Linux. We recommend temporarily acquiring a computer with Windows or Mac operating system. If that is not possible, it is essential to immediately inform the teacher.

Respondus - LockDown Browser

I downloaded Respondus LockDown Browser, but once launched it gives me problems with Chrome and asks me to close it.

Respondus activates a browser of its own, and it is normal for it to ask you to close all other applications, including Chrome. The program should be launched only when requested by the quiz and not before entering the quiz page.

Respondus - Connection problems

What are the bandwidth requirements for using Respondus?

Respondus requires a good and stable connection. It is recommended to use a wired connection and to check the connection speed, possibly carrying out an online speed test (for example with
The minimum bandwidth required for good connection is 130 Kbps. For further details see the following page.

My internet connection is unstable, what can I do?

We recommend that you check early enough whether your connection is stable. If not, you can use your mobile phone's connection via hotspot, if you find it more reliable. You will place your mobile phone far away from your desk.

Respondus - Simulation test

Can I do a test to understand how Respondus works?

Before taking an exam with Respondus, you must download the program and test its operation by doing one or more test quizzes at the link:
You must install Respondus and perform all tests a few days before the exam, so that you will have time to solve any problems if something does not work.

Respondus - Privacy

What data in my browser does Respondus access to?

It is an independent browser, a custom derivation of Chromium. In LockDown Browser there is therefore no information on the typical navigation of the user, since it is only used for examination. The company declares and guarantees the correct use of the data at the following links:

When I access the quiz I get the message: "There is a problem with the settings for this exam. Please notify your instructor that they need to access the LockDown Browser dashboard once in the new course to fix this problem".

It is a configuration of your computer, probably related to Windows 8.

There is currently no solution. Therefore, you need to get another computer or make arrangements with the teacher on a different examination method.
