I used the free trial in April - June while I was taking a course in data mining. I saw today that there is a one year license for students, a license that can be helpful for a new course that I am taking in my master's degree called Data Analytics in Sustainable Development, and for my thesis. Nevertheless, I haven't been able to install the educational license, so I was wondering if the reason could be that I already used a free trial. If it`s possible to use the educational license it would be great. So the question is, how can I install the educational license if the process described in the web page has not worked?
