I'm installing "Mathematica for Students" on my own home computer, but my license number doesn't be accepted.
The web site (https://register.wolfram.com/index.en.cgi) shows;

I had tried instlling this software on a lab's computer 8 days ago.
But I have understood that I cannot install Mathematica on a lab computer, by your e-mail.
So I uninstalled Mathematica on lab's computer.
