NI-USRP 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-USRP 15.0 is the version released with LabVIEW 2015 SP1. The last version released under the old numbering scheme is NI-USRP 1.3. The first version released under the new numbering scheme is NI-USRP 14.0.
For Windows XP, complete the following steps:
For Windows 7/Vista, complete the following steps:
For Windows 8.1, complete the following steps:
As part of the NI-USRP 15.0 installation, the following software is installed. To completely remove the NI-USRP 15.0 installation from your system, you must also remove all of the following packages:
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.
NI 294x/295x 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.

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:
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 National Instruments software on Microsoft Windows 8.x, 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.
NI Launcher helps you find and launch installed NI products. It provides you with a method of finding NI products similar to the Start menu in previous versions of Microsoft Windows. To use NI Launcher, click the NI Launcher tile in the Apps view. NI Launcher launches the desktop and opens a menu containing a list of NI products. Click any NI product to launch it.
|Note NI MAX does not appear as a desktop shortcut when installed on Microsoft Windows 8.x. You can launch NI MAX either from the Apps view or from within NI Launcher.|
For convenience, you can pin your most-used NI applications, such as MAX, to either the Start screen or the Taskbar on the desktop, as necessary.
|Current Application||Icon Location||Pin to Action|
|Windows 8.x Desktop||Desktop Taskbar||Right-click application and select Pin to Taskbar|
|Windows 8.x Desktop||Start screen||Right-click application and select Pin to Start|
|Windows 8.x Start screen||Desktop Taskbar||Right-click application and select Pin to taskbar from the menu bar on the bottom of the screen|
If you want to find a particular application or related files, such as documentation files, from the Start screen, you can access all installed files from the Apps view. To get to the Apps view, right-click anywhere on the Start screen and select All apps (Windows 8.0) or click the down arrow on the bottom left of the screen (Windows 8.1).
For more information about NI support for Windows 8.x, visit ni.com/windows8.
National Instruments NI-USRP will drop support for Microsoft Windows Vista and Windows XP as of July 1, 2016. Versions of NI-USRP that ship after July 1, 2016 will not install or run on Windows Vista, or Windows XP.
