Well I have just read things about it on Microsoft's website and everyone there says the same thing.. I've never seen this error before

ENBSeries doesn't change anything on system folders, and it also doesn't change the registry nor it includes itself on the registry. Here's how it works:
the programs (executables) that uses directx always verifies for directx (and other kind of) dll's on its own folder, and then use the system dll's for loading directx and so on. If there's nothing on its folder, it just loads system's directx dlls. If there's a dll on its folder, it loads both system and custom dll.

The difference between the dll on the game folder and the dll on the system folder is that the game's one is exclusive. This means it is only used by that game/program, and the remain of the system uses the system ones. Race Driver GRID for example has the d3dx9_37.dll included in its folder by default, this means that this specific dll will be only used by GRID, and if any other game needs it, it will search on the system folder for it instead of using GRID's one. I hope that make sense


Well if you want I can upload my system file for you but I don't know if it would solve the problem I have Windows XP Home Edition here (OEM).

Hi velociround,

Try to follow these steps:

d3dx9_37.dll
This is because you are missing a file.
Step 1. You can download http://www.d3dx9.net/download-missing-d3dx9_37-dll/ here.
Step 2. Paste this file into your system32 and system folder. Also put it in your syswow
Step 3. Navigate to your System32(32Bit OS) or SyWOW64(64Bit OS) Folder.
Note: The location of System32 or 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_37.dll into this folder.
Step 5.Run the game. It might work now.
