Make colors look better Win 7?

I\I have Lenovo T510, my cousin has Lenovo W520, and he uses Panton Color Calibrator to make colors look better, he's using Win 7 as well. I tried the same software but i get an error when i want to start calibration. Any ideas about a software that makes colors look better?

Hmm, that depends on your graphics card…

maybe you have an outdated graphics driver o.O
