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:
For more information about silent installations of individual NI products, refer to KB 4CJDP38M, Automating the Installation of a Single Installer.
For more information about silent installations of NI products in a suite, such as NI Developer Suite, refer to KB 4GGGDQH0, How Do I Automate the Installation of a Suited Installer?.
To determine what version of NI Installers your product contains, refer to KB 4CJDR18M, How Can I Determine the Type and Version of My NI Installer?.
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.com/windows10.
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. For more information about NI support for Windows 8.1, visit ni.com/windows8.
RFmx LTE Drops Support for Windows 7 (64-Bit) and Windows Server 2008 R2 in 2021
