Hmmmm, let me think.......help a student who should be using school computers for study and assignments to install SRO so that student can waste the opportunity of education on meaningless monster murder!??
Sure, what the heck
No, only kidding. Even if you could install it it would mean some hack to bypass your school's security measures, and you'd get yo azz booted when (and I do mean when not if) you get caught.
Give it up.
