Help needed ASAP

So I’m a college student trying to use this program for a Game Design class, yet it won’t work for me. I have a Dell Inspiron laptop, Windows 8.1, and meet all other needed requirements. However, when I open Unity, Windows says there was an issue and shuts the thing down. Can someone help me? This is for a grade.

Can you please send a screenshot of what exactly the window says. I’m happy to help, but I need to see the problem.
