    I am new to drivers and driver installers, so excuse me if this question is
    too basic :)

    We use the FTDI driver version 2.4.16 that supports both 32-bit and 64-bit
    Windows. For installing this driver we are using DPInst.exe

    According to this website:

    http://msdn.microsoft.com/en-us/library/ms790308.aspx

    DPInst version 2.1 supports later Windows and Vista versions. Does this mean
    64-bit Windows/Vista also?

    Or should I download one version for 32 bit and another for 64-bit
    Windows/Vista, as said here:

    http://www.microsoft.com/whdc/driver/install/32-64bit_install.mspx

    I would appreciate any help on this.

    Thanks.

    Well, it's not the SAME driver. 32-bit and 64-bit require different driver
    binaries.
    You should use a 64-bit DPInst on a 64-bit system. I don't have actual
    evidence that the 32-bit DPInst does not work, but I *do* know that
    installing drivers with the 32-bit DevCon causes confusing results. It
    appears to work, but the setup is not complete. Some parts of the install
    process only work from a 64-bit process.

    Both come with the WDK, so it's not a hardship.

    Tim,
    Thanks for responding. This answers my question fully.

    Where can I download the 64-bit DPInst.exe from?

    Thanks,
    GK.

    It should be provided with the WDK.

    Thank you, Mike. I ran the Kitsetup program to set up WDK. I have three
    directories - amd64, ia64 and x86, with a dpinst.exe in each.

    Which one should I use for 64-bit Windows/Vista? I am guessing the
    amd64/ia64. I tried searching the web for information on this, but found
    nothing.

    For some background I am a build/packaging engineer with no idea about
    device drivers. So excuse the extremely basic questions.

    Regards,
    GK.

    Really? The Server editions of Windows run on three different
    architectures: x86 (32-bit), x64/AMD64/EM64, and ia64 (Itanium). The
    client editions (like Vista) do not support Itanium, nor does anyone else,
    really.

    Unless you are working in a specialty environment, when you say "64-bit
    Windows", you mean the amd64 choice.

    DPInst.exe

    Another message appears when I select dpins_x86.exe showing "you have to run the 64-bit version of DPInst.exe on this machine. Contact the vendor that provided you this package." Does anybody have this version?
