You have to update your DirectX runtime.
Download it from here.
You don't need to uninstall the previous directx version.

Ps: If your game is installed, it's obvious there is no an Install option. You should uninstall the game first, and then will be an Install option. But it's unnecessary, just update your DX runtime.

As d3dx9_31.dll file is missing or corrupted, you need to get a new dll file. Here are the steps to replace d3dx9_31.dllfile

Step 1. You can download missing d3dx9_31.dll here:


Step 2. Paste this file into your system32 or SyWOW64 folder.

Step 3. Navigate to your System32(32Bit OS) or SyWOW64(64Bit OS) Folder.

Note: The location of System32 and SyWOW64 is

C:Windows\System32 (If you are using 32Bit Windows)
C:\Windows\SysWOW64 (if you are using 64Bit Windows)

Step 4. Paste the d3dx9_42.dll file into this folder.

Step 5. Try to run it. It might work now. If not, restart your computer to restore it effectively.
