NI-USRP 17.2 has the following requirements:
NI-USRP 17.2 supports the following operating systems:
Note NI-USRP 17.2 does not support Windows Server non-R2 editions.
NI recommends that you have the most recent service pack for your operating system installed.
Note In 2016, NI-USRP dropped support for Windows Vista, Windows XP, Windows Server 2003, and installations of Windows 7 without any service packs. NI-USRP 17.2 will not install or run on an unsupported OS. You cannot deploy or distribute applications that use NI-USRP 17.2 to an unsupported OS. Additionally, after installing NI-USRP 17.2, 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?.
Note Support for Windows 32-bit operating systems may require disabling physical address extension (PAE). To learn how this might affect your system and what actions you might need to take, visit ni.com/info and enter the Info Code PAESupport.
1 NI software installs VC2015 Runtime and .NET 4.6.2. 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.
2 NI software is signed with a SHA-256 certificate. Windows 7 SP1, Windows Embedded Standard 7 SP1, and Windows Server 2008 R2 SP1 require Microsoft updates to support SHA-256. Refer to Microsoft KB3033929 for more information about how to install this security update.
NI-USRP 17.2 supports the following application software versions, including service packs. You should install application software, such as LabVIEW, LabVIEW Communications System Design Software, or LabVIEW Communications System Design Suite, before installing NI-USRP. To add support for application software installed after installing NI-USRP, modify your NI-USRP installation or launch the NI-USRP installer again.

NI-USRP includes several example applications for LabVIEW. These examples serve as interactive tools, programming models, and as building blocks in your own applications. NI-USRP includes examples for getting started and other software-defined radio (SDR) functionality. You can access the NI-USRP examples from the following locations:
Note The NI Example Finder does not include NI-USRP examples.
USRP RIO includes several sample projects for LabVIEW. These sample projects serve as starting points to build a USRP RIO streaming application. To access the LabVIEW sample project from the Create Project dialog, select Sample Projects in the left pane and navigate to the NI-USRP Simple Streaming project.
You can access additional examples from the Code Sharing Community at ni.com/usrp.
USRP RIO devices support both 1G Ethernet and 10G Ethernet using the connectors on the device back panel. With the default FPGA image, port 0 is designated for 1G, and port 1 is designated for 10G.
The USRP-2974 is only supported through Ethernet using 1 GbE through RJ45 and 10 GbE through SFP+ connections.
Note The FPGA cannot be modified when the USRP RIO device is connected through Ethernet.

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.
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:
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.com/windows10.
When you install NI 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. For more information about NI support for Windows 8.1, visit ni.com/windows8.
