SDL MultiTerm 2017 Extract failed to extract any terms

I am a Translation major student. During my CAT course, I tried to use SDL MultiTerm 2017 Extract on the school's PC to extract terms from a passage, but never succeeded!

Nevertheless, the exactly same app works well on my teacher's teaching PC. I noticed that there is always a prompt appears before the extracted term list is shown, which never happened in students' PCs. So I think it is because the prompt does not appear that we cannot see the term list.

So my question is: how to make the prompt appears?
