I'm not familiar with the software in question, but I'm quite sure it'd still be possible to have someone else to sit your exam. For instance, you could have an external webcam pointed at yourself, and have someone else in front of your computer writing the actual exam. Maybe even mirror the display so that you can see what your accomplice is doing.

I had experience having an exam with the proctorio. And I see many ways how it can be cheated, at least technically. They also say they monitor your head and eyes movements, which is supposed to show something unnatural if you're cheating. Though I'm not sure it's really possible, and maybe just a security theater.
