I appreciate your effort but unfortunately it is not working :(

Mr.Ahmed,

You go to PLAXIS official web site www.plaxis.in and there is a free download student versions. You click on this tool and register yourself. After verifying your official institute e-mail id then, you can download free version. The free version is as good as original version. This free version is only for one month..also, general free 1-month version also available in official web site..ok all the best..

You can download the student-free version software from PLAXIS website.
