DirectX D3DX DLLs
In previous versions of the DirectX SDK, D3DX was statically linked. Current versions use a DLL instead. Unfortunately, with each minor update of the SDK, a new version of this DLL was created. Many people find they cannot run simple programs they download from the net because they miss a file such as D3DX9_25.DLL.
Fortunately GameDev.net forum member Keith Ditchburn (Trip99) has created installers for these files. To help him out with the bandwidth requirements, I've mirrored the files below. Please download just the file you need.
