01 — Solução passo a passo

Solução passo a passo

  1. STEP 01

    Download DirectX End-User Runtime

    Get dxwebsetup.exe from Microsoft's official page (microsoft.com/en-us/download/details.aspx?id=35).

  2. STEP 02

    Run the installer

    Untick the Bing Bar offer and continue. The installer downloads missing DirectX 9 components automatically.

    Even with DirectX 12 on Windows 10/11, old games request DirectX 9 libraries — this adds only the missing pieces.

  3. STEP 03

    Restart the computer

    Reboot after setup and launch the game again.

  4. STEP 04

    If it persists, verify game files

    Run file verification/repair from Steam, Epic Games etc. Broken DLL copies are replaced automatically.

  5. STEP 05

    Also install Visual C++ packages

    If MSVCP140.dll warnings accompany the error, install the Visual C++ 2015-2022 package too.

Dicas

  • The installer needs internet; disable VPN/proxy if it fails.
  • One install fixes every old DirectX 9 game on the PC.

02 — Perguntas frequentes

Perguntas frequentes

Which games throw D3DX9_43.dll errors?

Mostly pre-2010 DirectX 9 titles: older GTA, FIFA and Call of Duty releases and many classic shooters. Windows 10/11 doesn't include these components by default.

Setup says DirectX is already installed?

dxwebsetup.exe adds only missing components and works independently of the installed version. 'No components needed' still means success.

Does copying the DLL to System32 work?

It may appear to, but it's risky: wrong versions cause more errors and DLL sites can serve malware. The official installer places the right file in the right place.
