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 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.
NI installs RFmx LTE using NI Package Manager. If you do not already have NI software installed, RFmx LTE installs NI Package Manager to handle the installation of your NI software. 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.

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:
