my cubase 8 AI doesn't run

HEEEEELP!!!
Why my cubase is so bad with me?
I installed on my win 10 (64 bit) pc both version (32 & 64) but no one runs.
When the Cubase boot arrive at “Player Video” everything stops and it crashes.
Could someone help me?

Hi,

Install the latest Quick Time Player, please.

Hey Guys.
Problem solved.
It wasn’t a prpblem caused by quick time (i already installed it…). It was a video card problem.
Changed card and problem solved.
Anyway…many thanks to everybody

C u at the next problem

Bye
