Unable to start Unity 3D on Windows 7

When attempting to start the software, unfortunately I come across with an error as displayed in the image below.

Unity Editor
Unity Editor has stopped working
Windows can check online for a solution to the problem.
Check online for a solution and close the program
Close the program
I am stuck in a dilemma, the Unity Editor was halted. Will Windows look for a remedy to lick this trouble or simply end or close it?
Which do you think is better? Please help!
