    "Error: d3dx9_43.dll is missing, The application failed to start" on Windows 8

    Whenever I try to open any of the installed applications on my Windows 8 machine am getting the message "Error: d3dx9_43.dll is missing, The application failed to start", but I don't know who has deleted the dll files from my machine. I don't even know the method to restore them, please help me to fix this message and run all the apps normally.

    Hi Friend,

    You are receiving an "Error: d3dx9_43.dll is missing, The application failed to start" on Windows 8

    There is due to following reasons,
    >> the directX is not installed
    >> may be directX version is not match that files
    >> also installation file require the directx version 9 to run it.

    So, you can Download the d3dx9_43.dll from internet
    And paste into System32 folder
    Restart PC
    your problem is solved,

    if issue persists Download the DirectX 9 from interet
    and install it.

    I hope you will understood.

    All the Best.

    Hello there !!!

    we are hundred percent sure that your system
    has been infected.
    since your .dll file is getting deleted which is the runtime file
    that helps the application to get launced in the system
    and help the applicatrion to be properly run on to the machine.

    so download the antivirus ,scan the system.
    your issue will be rectified.

    hope i am clear to you.
    thanks for posting in EALP.
