      System Requirements: The driver installation will check for the
      following requirements.  If not found, the installer will either
      abort, warn, or install the required component as appropriate.
      Supported Operating Systems:
        Windows 8
    	Windows 8.1
        Windows 10
      Shared Components
        Before this driver can be installed, your computer must already
        have the IVI Shared Components installed.
        Minimal IVI Version: 2.4.2
        The IVI Shared Components installer is available from:
        Any compliant implementation is acceptable. Typically, VISA-COM is
        installed with VISA and other I/O library modules. 
    Additional Setup
      .NET Framework
        The .NET Framework itself is not required by this driver. If you
        plan to use the driver with .NET, the minimal .NET framework version is 2.0.
      The .NET Framework requires an interop assembly for a COM
      server. A Primary Interop Assembly, along with an XML file for
      IntelliSense is installed with the driver. The driver's PIA, along
      with IVI PIAs are installed, by default, in:
      :Program FilesIVI FoundationIVIBinPrimary Interop Assemblies
      The PIA is also installed into the Global Assembly Cache (GAC) if
      you have the .NET framework installed.
