DayZ wont launch -

[Raf]

Thanks for your help.

I have read a lot of posts on similar topics, but they appear to be different to mine. I have tried a lot of the things in the other posts.

Summary;

I have just purchased a second hand gaming desktop PC. Good little rig I think.
Clean install of windows 8.1 on a new hard drive.
Installed Steam, and downloaded Dayz

My problem is that when click PLAY r the desktop shortcut, it says;

"Do I want to allow Steamservice.exe to make changes to my hardrive".

I click yes, and then is say,

"Performing first time set up-
"Installing Microsoft Directx for windows (1 of 1)

and then.....nothing.

Seems to register me having played, i.e., changes the summary info on Dayz to say "Last played - Today"

Background;
I have Steam and DayZ on my other laptop, and Dayz launches well there. However, something is not right on the new PC.

Cheers
Raf

Install DirectX End-User Runtime if your application or game requires an earlier version of DirectX

Some applications and games require DirectX 9. However, your computer includes a more recent version of DirectX. If you install and then run an application or game that requires DirectX 9, you might receive an error message such as "The program can't start because d3dx9_35.dll is missing from your computer. Try reinstalling the program to fix this problem."

To resolve this issue, go to the following Microsoft website to install DirectX End-User Runtime:
DirectX End-User Runtime Web Installer

Note When you run this package, no change is made to your version of DirectX, Direct3D 9, Direct3D 10.x, Direct3D 11.x, DirectInput, DirectSound, DirectPlay, DirectShow, or DirectMusic.
