Why won't Thief start?

I click on play and even the launcher won't start. The steam preparing the launch and after that nothing happen.

I posted this in another post, this solution worked for me.

Found one solution that worked for me.
Found the information on this website: http://www.gameskinny.com/j0qk9/thief-2014-steam-black-screen-other-common-issue-fixes

I did this: In the part that says Game Won't launch at the bottom there are instructions to download some dll files and to copy them to your system32 folder. Don't copy them in to that folder. Read the PLEASE NOTE section:

"DO NOT personally recommend mucking around your System32 files without any advanced knowledge. I suggest this alternative step which other users have found to work instead. After downloading and extracting the files in the URl above, open it and copy the .dll files inside. Then, go into your Steam\SteamApps\common\thief\Binaries folder and paste them in either the win32 or win64 (depending whether your system is 32- or 64-bit) folder."

I did that instead, I downloaded the files and copied them to my:
C:\Program Files (x86)\Games\Steam\SteamApps\common\Thief\Binaries\Win64
because i have a 64-bit system, or you copy them into the Win 32.

After that launch the game via the "Shipping-ThiefGame.exe" and it worked for me. No need to mess around in your windows System32 folder.

Hope it works for you.
