LabVIEW NXG Support and Considerations
The following sections detail considerations for using LabVIEW NXG 5.0 with FlexRIO 21.5.
LabVIEW NXG Operating Systems and System Requirements
Software support for LabVIEW NXG differs in the following ways:
System requirements—Only 64-bit (x64) processors are supported.
Operating system—Only 64-bit operating systems are supported. Refer to the Supported Operating Systems section for more information.
View context help in LabVIEW by pressing <Ctrl-H> and hovering over an object.
Search for items using the search bar in the upper right corner of the LabVIEW window. You can also view context help for the search results.
Additional documentation is available online at ni.com/manuals.
LabVIEW NXG Examples
Launch LabVIEW and click the Learning tab.
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.
If the NI product you are installing uses Microsoft .NET 4.6.2, 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 4.6.2 separately before you install NI software.
For more information about automating the installation of NI products, refer to Automating an Installer in the NI Package Manager manual.
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, refer to NI Product Compatibility for Microsoft Windows 10.
