I can't play Need for Speed Unbound on a different Drive

I got the game on Steam.

When I want to install the game on a different Drive, my game won't start. That fucking EA App doesn't know the game is installed. It pops a text which says "the game gets prepared" and steam verifys the game everytime when I try to launch it.

But when I install it on the drive, I installed it before, it works. No pop ups. The EA App sees the game is installed. Everything works fine.

Problem: The game is installed on a HDD and I want it on a SSD.

Why can't I install it on a different Drive?

I hope you guys can help me.
