Installing the software on Microsoft Windows
      
    Unpacking the .zip archive:
    You will need to unzip the downloaded file in the location you have
    chosen to hold the executable files (perhaps somewhere like \bin). I would NOT put them in \Program Files, since spaces in
    directory or file names and command line environments are a very bad
    mix, and will cause you endless problems. The archive will create a
     top level directory Argyll_VX.X.X, where X.X.X is
    the version number, and the executables will be in Argyll_VX.X.X\bin.
    Making the tools
        accessible:
    You should also configure your %PATH% environment variable to give
    access to the executables from your command line environment.
    
    For Windows 8, 8.1, 10
      & 11, look in
        Desktop
    -> Settings -> Control Panel -> System And Security ->
    System -> Advanced System Settings -> Environment Variables
    
    For Windows 7, look in
        Start Menu -> Control Panel -> System And
    Security -> System -> Change Settings -> Advanced ->
    Environment Variables
    
    For Vista, look in
        Start Menu -> Control Panel -> System And
    Maintenance -> System -> Change Settings -> Advanced ->
    Environment Variables
    
    For XP look in
        Start->Settings->Control
    Panel->System->Advanced->Environment Variables
    
    You want to add the directory you've chosen to your %PATH%, which is
    a System Variable. Normally you would add this to the end of the
    current setting, separated by a ';'.  
    
     So if the current value of PATH is
    "%SystemRoot%\system32;%SystemRoot%" and you unpacked Argyll version
    3.1.0 in d:\bin\, then you
    would modify PATH to be
    "%SystemRoot%\system32;%SystemRoot%;d:\bin\Argyll_V3.1.0\bin", -
    i.e. you append the path to the Argyll binaries to your PATH,
    separated by the ';' character. The change will take effect when you
    start a new command shell, which you start from Start
    Menu->Accessories->Command Prompt, or Start
    Menu->Programs->Accessories->Command Prompt. You can check
    that the environment variable has been set by running the command
    "echo %PATH%" in the command shell.
    
    The .zip file also contains several useful reference files (such as
    scanner chart recognition templates, sample illumination spectrum
    etc.) in the ref sub-directory, all the current documentation in a
    doc sub-directory, and instrument USB drivers in the usb directory.
    
    NOTE: Vista 64/Windows 7, 8,8.1,10 &
      11  64 bit and Beep
    prompt: Microsoft (in its
    infinite wisdom) has removed the built in speaker driver, and now
    relies on systems having a sound card and speakers's installed and
    turned on to hear system beeps. So if you're wondering where the
    beeps have gone when using chartread,
    now you know.
    
    NOTE: Microsofts generic VGA Driver
    does not appear to support setting the graphics card VideoLUTs. You
    will need to install a display driver for your specific display
    hardware to enable this. Note also that it is possible in many cases
    to use Windows 7 video drivers on Windows 8 systems etc.. If you are
    having trouble accessing the VideoLUTs, then check in Device Manager
    that you are running the correct driver for your card, and not using
    the fallback generic driver.
    
    
    NOTE that if you wish to use
    Argyll tools (dispwin) to control display
    calibration, that you will have to disable any other display
    calibration loader programs.
    Other
          software that may interfere with display calibration loading
          and USB instrument access:
    There are other programs that will interfere with calibration
    loading, such as igfxpers.exe that gets installed with nVidia
      "Optimus" technology.
    You may have to disable both the igfx tray module
    (c:\windows\system32\igfxtray.exe) and the igfxpph Module
    (c:\windows\system32\igfxpph.dll) in addition to the persistence
    Module (c:\windows\system32\igfxpers.exe).
    
    A good tool for this is AutoRuns.
    Note that the igfxpph module may exist in several locations and you
    have to disable all of them. Reboot after changing settings.
    
    It has also been reported that some RGB LED driver services will
    interfere with USB instrument access. A known culprit is the Logitech
      LampArray Service which may be have been installed with
    Logitech software or by default in MSWindows 11. Other RGB
      LED drivers and services such as Gigabyte RGBFusion
    have also been reported as interfering with USB instrument access.
    You may need to identify all such services and disable or uninstall
    them.
    
    Also reported to interfere with access to instruments, is TeamSpeak3.
    You may need to disable or upgrade to TeamSpeak5 to avoid issues.
    Some services are reported to interfere with access to instruments,
    such as Mountain's BaseCamp.Service. You may need to disable
    or uninstall this service for instruments to be recognized.
    
    
    Serial
          Instruments:
    
    If you are using a serial connected instrument, then there is
    nothing special to do to enable this.
    USB Instruments:
    If you are using a USB connected instrument, then suitable USB system drivers may need to
    be installed.
    
    Note that the Huey,
    i1 Display Pro, ColorMunki Display and ColorHug
    colorimeter appears as an HID (USB Human Interface Device
    Class) device, and hence will be assigned to the default MSWindows
    HID driver. You therefore don't need to install an
    Argyll usb system driver
    for these instruments, although it is possible to select the
    libusb0.sys driver as an alternative to the default HID driver.
    
    If you are using the JETI specbos 1211, 1201,
      1511, 1501 and the Klien K10A then you may need
    to install the FTDI
      Virtual COM Port Drivers (VCP), if they are not already on
    your system. You may have to update to the latest FTDI driver to
    work with the FTDI FT231XS chip that the JETI specbos 1511,
      1501 use.
    
      
    
    For all operating system versions you can
    install the ArgyllCMS libusb0.sys driver by navigating to your
    ArgyllCMS installation usb directory, and running ArgyllCMS_install_USB.exe.
    This will trigger a UAC prompt which you will have to agree to to
    proceed. You may have to re-plug an instrument for the new driver to
    be picked up.
    
    To uninstall the ArgyllCMS libusb0.sys driver, navigate to your
    ArgyllCMS installation usb directory, and run ArgyllCMS_uninstall_USB.exe.
    This will trigger a UAC prompt which you will have to agree to to
    proceed.
    
    If you need to update the driver because support for a new
    instrument has been added, then run  ArgyllCMS_uninstall_USB.exe
    followed by ArgyllCMS_install_USB.exe.
    
    Using
        Argyll drivers with existing OEM drivers:
        
       If you currently have applications other than
    Argyll accessing your USB connected instrument, then you will have
    to manually install the Argyll driver, and then switch back and
    forth between the Argyll and other drivers if you want to switch
    between applications.
    
    If you are using a recent version of Microsoft Windows and want to often
    switch between using ArgyllCMS and the OEM driver, you can try using
    a different physical USB port for each installation, as this
    reportedly avoids the need to manually switch drivers.
    
     Jump to your operating system version for the details of how to
    switch drivers:
    
    Windows 8, 8.1, 10 & 11
    Windows 7
    Windows Vista
    Windows XP

        Right click on instrument -> Update Driver
    Software... -> let me pick from a list of device drivers on my
    computer
        (Choose either the Argyll driver or another
    driver from the list)
