The thing is that I used to be a mechanical designer, but last year I took a break on my career, however, I feel I'm losing practice and was thinking on play around with the new versions, of course since I'm not working in an engineering firm anymore I do not have acces to a license and I don't know if it is still possible to install the software as demo, and if it is still possible, could be done with a newer version (SW 2020) in a computer wich once had SW 2018 installed (with a licence of course).

I want to join the labor market again, so wanted to be up to date on my skills, 30 days would be good to practice.
