Hi all,

I installed a game and was not able to play it; after scouring the internet, I found that the following DLL file was missing - d3dcompiler_43.dll.

I downloaded the DirectX End-User Runtime Web Installer, but after opening the .exe file, the following error was shown.

What am I doing wrong?

    Yes, Extract from the two .cab files you mentioned.

    i.e.,

    • Jun2010_D3DCompiler_43_x86.cab
    • Jun2010_D3DCompiler_43_x64.cab

    And the error occurs if you copy from the cab file to System32 or SysWOW64 directly.

    Instead, copy to the desktop and then move the file to System32 and SysWOW64.

    So to confirm, I should extract from the "Jun2010_D3DCompiler_43_x86.cab" and "Jun2010_D3DCompiler_43_x64.cab" files?

    Please suggest how I can get past the "Access denied" prompt.

    Hi sumedhborkar,

    You're correct about the .cab file names.

    1. Have you extracted the DLLs from the mentioned cab files?
    2. Is your account an admin account?

    Hi,

    Download the full installer from https://www.microsoft.com/en-gb/download/details.aspx?id=8109

    Double-click the file and mention a folder where the .cab files will be extracted.

    Use 7-Zip to extract d3dcompiler_43.dll from:

    • Jun2010_d3dx9_43_x86.cab (32-bit DLLs)
    • Jun2010_d3dx9_43_x64.cab (64-bit DLLs)

    Copy the x86 d3dcompiler_43.dll to C:\Windows\SysWOW64.

    Copy the x64 d3dcompiler_43.dll to C:\Windows\System32.
