This is caused by the lack of DirectX 9 in the system. Some old games require the support of DirectX 9. Installing DirectX 9 can solve the problem!

Windows 10 and Windows 11 are missing d3dx9_43.dll solution:

For some games that use D3DX9, D3DX10, D3DX11, XAudio 2.7, XInput 1.3, XACT, and/or Managed DirectX 1.1, the Microsoft DirectX® End-User Runtime installs many runtime libraries from older versions of the DirectX SDK.

Microsoft DirectX® is included in Windows XP Service Pack 2, Windows Server 2003 Service Pack 1, Windows Vista, Windows 7, Windows 8.0, Windows 8.1, Windows 10, and Windows Server equivalents. This DirectX End-User Runtime does not change the version of DirectX, but it installs many optional side-by-side technologies used by some older games from the Legacy DirectX SDK. For detailed instructions, see https://aka.ms/dxsetup.

Note that Desktop Bridge applications using D3DX9, D3DX10, D3DX11, XAudio 2.7, XInput 1.3, or XACT must use Microsoft.DirectX.x86/Microsoft.DirectX.x64 framework to deploy these legacy DirectX SDK side-by-side components. Alternatively, developers can remove all such dependencies. For more details, see Microsoft Docs
