Gears of War Installation

I've been trying to install Gears of War on my PC and whenever I tell the game to install to my D drive it installs to my C drive instead.

What's going on here?

Not enough space on D drive? That's the only thing I can think of.Vilot_Hero

I think 200gb is more than enough space to run GoW, not to mention my C drive has about 13gb lol.
