System Requirements

Supported Operating Systems

NI-VNA 17.0 supports the following operating systems:

  • Windows 101/8.11,2/7 SP13 (32-bit and 64-bit)
  • Windows Server 2012 R2 SP12 (64-bit)

1 NI-VNA requires Microsoft .NET Framework 2.0, which is not automatically installed with Windows 10 and Windows 8.1. Refer to Microsoft KB2785188 for more information about how to enable .NET Framework 3.5, which includes .NET Framework 2.0.

2 NI software installs VC2015 Runtime and .NET 4.6.1. Windows 8.1 and Windows Server 2012 R2 require Microsoft updates to support these items. Refer to Microsoft KB2919442 and KB2919355 for more information about how to install these updates.

3 NI software is signed with a SHA-256 certificate. Windows 7 SP1 requires Microsoft updates to support SHA-256. Refer to Microsoft KB3033929 for more information about how to install this security update.

Note:  NI-VNA 17.0 does not support Windows Server non-R2 editions.

Note  In 2016, the PXI-5690 dropped support for Windows Vista, Windows XP, Windows Server 2003, and installations of Windows 7 without any service packs. The PXI-5690 will not install or run on an unsupported OS. You cannot deploy or distribute applications that use the PXI-5690 to an unsupported OS. Additionally, after installing the PXI-5690, you cannot use any installers built on this computer with any version of LabVIEW, LabWindows™/CVI™, NI TestStand™, or Measurement Studio on an unsupported OS.

For more information about the changes to our OS support for 2016, refer to KB 79UC78LS, Why Does my LabVIEW, LabWindows/CVI, Measurement Studio, or TestStand Built Installer Fail on Windows XP/Vista and Server 2003?.

NI recommends that you have the most recent service pack for your operating system installed.

Minimum System Requirements

  • A screen resolution of 1,024 x 768
  • Windows 10/8.1/7, with all available critical updates and service packs

Application Development Environments (ADEs)

Note  You should install ADEs, such as NI LabVIEW, NI LabWindows™/CVI™ or Microsoft Visual Studio®, before installing NI-VNA. To add support for ADEs installed after installing NI-VNA, modify your NI-VNA installation or launch the NI-VNA installer again.

  • NI LabVIEW 2014 SP1, 2015 SP1, 2016, or 2017

Accessing VIs and Functions

NI–VNA palette VIs are available from the Functions»Measurement I/O»NI–VNA palette.

NI–VNA functions are available in LabWindows/CVI from the Instrument menu. To load the NI–VNA function panel (.fp), select Instrument»Load, and navigate to IVI\Drivers\niVNA\niVNA.fp.

Finding Examples

In LabVIEW, you can use the NI Example Finder to search or browse examples. NI–VNA examples are classified by keyword, so you can search for a particular device or measurement function. In LabVIEW, select Help»Find Examples to launch the NI Example Finder. The NI Example Finder offers two ways to access all installed LabVIEW example VIs and their descriptions:

  • Click the Browse tab to locate examples by task at Hardware Input and Output»Modular Instruments»NI–VNA or by directory structure at instr»niVNA.
  • Click the Search tab to search all installed examples by keyword. For example, search for "VNA" to locate all NI RF vector network analyzer examples.

The NI Example Finder is also available in LabWindows/CVI by selecting Help»Find Examples.

You can also access all the installed NI–VNA examples for LabVIEW and LabWindows/CVI at Start»All Programs»National Instruments»NI–VNA»Examples.

Driver Version Naming Changes

NI-VNA versions are now aligned with the versions of major NI application software products. This alignment gives you information about the year the driver was released and the most recent software version the driver was designed to work with. Driver versions now start with a two-digit year indicator: <ProductName><Year-BasedVersion>. For example, NI-VNA 14.0 is the version released with LabVIEW 2014. The last version released under the old numbering scheme is NI-VNA 2.0.1. The first version released under the new numbering scheme is NI-VNA 14.0.

Uninstalling NI-VNA

As part of the NI-VNA 17.0 installation, the following software is installed. To completely remove the NI-VNA 17.0 installation from your system, you must also remove all of the following packages:

  • NI Measurement & Automation Explorer (MAX) 17.0
  • NI-VISA Run-Time Engine 17.0

Caution  Several of the software packages listed above are shared with other NI software packages. If you attempt to remove a piece of software that something else is dependent on, a message launches to warn you about the software dependencies. You can choose to either uninstall all of the software or to leave the shared software installed. If you choose to uninstall the shared software, some of your other NI software may no longer function correctly.

Note  Do not attempt to uninstall by manually deleting files.

IVI Compliance Functionality

NI-VNA 17.0 no longer installs IVI Compliance Package. NI-VNA 17.0 supports IVI configuration and runtime, but no longer supports the following features:

  • LabVIEW and SVI IVI class driver APIs for developing IVI interchangable applications.
  • IVI Class Simulation Drivers.
  • IVI-COM Adapters.
  • If you want to the above features, you must install IVI Compliance Package separately, either from or from the NI Device Drivers 2017 DVD.

    Known Issues

    You can access the software and documentation known issues list online. Refer to the NI-VNA 17.0 Known Issues at for an up-to-date list of known issues in NI-VNA 17.0.

    Licenses and Notices

    NI-VNA contains third-party software for which the following licenses and notices apply:

    Automating the Installation of NI Products

    You can automate the installation of most NI products using command-line arguments to suppress some or all of the installer user interface and dialog boxes. However, starting with the August 2012 releases (products using NI Installers version 3.1 or later), you may need to perform additional steps before or during a silent installation of NI software.

    If the NI product you are installing uses Microsoft .NET 4.0, the .NET installer may run before any NI software installs and may require a reboot before the installation of NI software begins. To avoid a .NET reboot, install .NET 4.0 separately before you install NI software.

    For more information about automating the installation of NI products, refer to the following KnowledgeBase articles:

    Using NI Software with Microsoft Windows 10

    Microsoft Windows 10 is the latest version of the Windows operating system and features significant changes compared to previous versions. Windows 10 introduces several new capabilities and also combines features from both Windows 7 and Windows 8. For more information about NI support for Windows 10, visit

    NI-VNA requires Microsoft .NET Framework 2.0, which is not automatically installed with Windows 10 and Windows 8.1. Refer to Microsoft KB2785188 for more information about how to enable .NET Framework 3.5, which includes .NET Framework 2.0.

    Using NI Software with Microsoft Windows 8.1

    When you install National Instruments software on Microsoft Windows 8.1, you will notice a few additional tiles in the Apps view, including shortcuts to NI application software products such as NI LabVIEW, Measurement & Automation Explorer (NI MAX), and NI Launcher.
