WDDM 1.1 driver for Intel 945 Express Chipset Family


  • Hello, I am using Dell Inspiron 640m laptop along with Windows 7 Ultimate. I have successfully installed WPDT. The problem I am facing is that when I launch a template Windows Phone Application, the emulator show up and disappears giving the error "The object invoked disconnected from the client". Sometimes, the error is "The interface is unknown".

    After some research, I have reached a conclusion (Please correct me if I am wrong) that driver for my Intel 945 Express Chipset is not WDDM 1.1 compliant. I have done enough research but could not find the updated driver anywhere. Can anyone please guide me to resolve this issue? I am pasting the DirectX Diagnostics information below for your reference. Thanks in advance.

    You're system RAM does not meet minimum specs.  You need at least 2Gb of RAM in order to use the emulator reliably.

  • I suggest you try Intel's update utility to check for a newer driver:

    Your RAM can be expanded cheaply and easily if necessary.

  • Thanks for the response. Intel's update utility says that I have the latest drivers (WDDM 1.0)
    I have also heard of some kind of mod drivers as a workaround to this problem. Has anyone used them?
