Note In 2019, RFmx LTE dropped support for all 32-bit Windows operating systems. RFmx LTE will not install or run on an unsupported OS. Refer to RFmx LTE Drops Support for Windows 7 (64-Bit) and Windows Server 2008 R2 in 2021 for information about future OS support.
RFmx LTE supports the following application software versions, including service packs. You should install application software, such as LabVIEW, LabWindows/CVI or Microsoft Visual Studio®, before installing RFmx LTE. To add support for application software installed after installing RFmx LTE modify your RFmx LTE installation or launch the RFmx LTE installer again. If you are not using NI application software, refer to Microsoft Visual Studio Support.
|Application Software||Versions Supported by RFmx LTE|
|LabVIEW||2016, 2017, 2018 SP1 f4 patch, or 2019|
If you are using the RFmx LTE .NET Class Library, .NET Framework 4.0 (minimum) is required. The RFmx LTE .NET Class Library can be used with Visual C# or Visual Basic .NET in any Visual Studio version that can target .NET Framework 4.0.
To use the .NET API, you must install the .NET class libraries or the .NET wrapper in addition to the NI device driver. For information about versions of the .NET Framework and the drivers each supports, as well as the download location of the installer files, refer to National Instruments .NET Driver Support.
NI automates RFmx LTE installation using NI Package Manager. Visit ni.com/info and enter the Info Code NIPMDownload to download NI Package Manager. Refer to the NI Package Manager Manual for more information about installing, removing, and upgrading NI software using NI Package Manager.
RFmx LTE is available for download from NI Software Product Downloads.

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 8.1, 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.
RFmx LTE will drop support for Windows 7 (64-bit) and Windows Server 2008 R2 starting in 2021. Versions of this product that ship after May 1, 2021, will not install or run on these operating systems. For detailed information about NI operating system support, visit ni.com/r/win32bitsupport.
