JSI Tip 9082. When you install DirectX 9.0 on Windows XP Professional, you receive 'DirectX did not copy a required file'?

When you run Dxwebsetup.exe to install DirectX 9.0 on Windows XP Professional, you receive:

DirectX did not copy a required file.

Even though this error is displayed just after the D3dref8.dll file is copied to your computer, D3dref8.dll cannot be found.

The behavior occurs if the %SystemRoot%System32DxxpdbgDxxpunp.inf file, a DirectX debug component, exists on your computer.

To resolve this problem:

1. Open a CMD.EXE window.

2. Type cd /d %SystemRoot%system32dxxpdbg and press Enter.

3. Type del /q Dxxpunp.inf and press Enter.

4. Type exit and press Enter.

5. Run Dxwebsetup.exe to install DirectX 9.0.
