Look my old PC

[FireXc]

Hi guys,

Im new on dolphin universe and i want to give new life to my old PC.
Actually i have a laptop but it is only for work purpose, so you can imagine that games hardly can be emulated.
In the other hand i have my old-decent PC coming back to life.
Here is the specifications:

CPU: Intel Core2Quad Q9550 (@2.85ghz)
GPU: Ati Sapphire Toxic edition HD4850 (RV770)
RAM Corsair Dual-channel 4GB DDR2
Motherboard: MSI P45-Neo

I have test some games and i can say there is not problem. Some issues appear with NSMW, especially with sound. If i turn off the sound the game goes like a charm. If i turn on it, everything goes wrong.
I have tried to configure the video on dolphin emulator, and here is my question:
When i try to set the graphics as "Direct 3d/Ati hd 4800 series", dolphin indicates the following error: "Failed to load D3DCompiler_42.dll, update your DX11 runtime, please"
I'm running a clean installation of Windows 7 ultimate fully updated.
How can i fix it?

if you have any suggestion i will appreciate.

Done. That was the problem.
Thx.

By the way, sound issues still happen.
