X3DAudio1_6.dll is missing from my computer, can't run?

[Aresous]

I have a little issue with running the game. Here's the window that pops up:

"The program can't start because X3DAudio1_6.dll is missing from your computer. Try reinstalling the program to fix this problem."

What should I do to fix this, download X3DAudio1_6.dll from somewhere? If so, do you know where I can get it from with a safe download?
Or another solution?
Thanks,

This hasn't helped me, but maybe it will if you answer my questions within this quote?

Everyone receiving ARMA 2 crash or fail to start due to xaudio or x3daudio etc.

Download and run DirectX Web Setup.
Let it download and setup directx, maybe need reboot after. Try to run game again.
