When you run the DirectX Diagnostic Tool (Dxdiag.exe), the following files may be listed as the "Debug" version of the files on the DirectX Files tab:
  • D3d8d.dll
  • D3dx8d.dll
  • Dinput8d.dll
  • Dmbandd.dll
  • Dmcompod.dll
  • Dmimed.dll
  • Dmloaded.dll
  • Dmscripd.dll
  • Dmstyled.dll
  • Dmsynthd.dll
  • Dmusicd.dll
  • Dswaved.dll


This behavior occurs if you uninstall the Microsoft DirectX Software Development Kit (SDK), and then install the Microsoft DirectX Runtime program.

More information

The Notes section on the DirectX Files tab contains a recommendation that you reinstall DirectX to correct the issue. However, if you reinstall DirectX, the files are not updated. In addition, the "Debug" files function correctly after you install the DirectX Runtime program.

NOTE: Most of the "Debug" files are not used by the retail version of DirectX.
