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.

LabVIEW lessons are located in the Lessons tab, and LabVIEW Examples are located in the Examples tab. Follow the instructions in the lessons and examples.

IVI Compliance Package Functionality

NI-DCPower no longer installs IVI Compliance Package. NI-DCPower supports IVI configuration and runtime, but no longer supports the following features:

  • LabVIEW and CVI IVI class driver APIs for developing IVI interchangeable applications
  • IVI Class Simulation drivers
  • IVI-COM Adapters

If you want to use the above features, you must install IVI Compliance Package separately, either from ni.com/downloads or from the NI Device Drivers 2018 DVD.

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.

Unsupported Windows Operating Systems
