Supported Platforms

The Real-Time Module supports the following operating systems for application development:

  • Windows XP Pro (Service Pack 2 or 3)
  • Windows Server 2003 R2 (32-bit)
  • Windows Server 2008 R2 (64-bit)


  • The Real-Time Module is compatible with 32-bit LabVIEW only. Therefore, you must have 32-bit LabVIEW installed even if you use a 64-bit OS.
  • Support for Windows Server 2003 R2 may require disabling physical address extensions (PAE). Refer to the National Instruments website for information about how this might affect your use of Windows Server 2003 R2 and what actions you might have to take.
  • The Real-Time Module does not support the Windows Server non-R2 editions.

The Real-Time Module installs the following real-time operating systems (RTOSes). Refer to the specific RT target hardware documentation for information about which RTOS your target uses.

  • NI ETS 13.1
  • VxWorks 6.3

Note:   Each RTOS supports only a subset of LabVIEW features. Refer to the Real-Time Module»Unsupported LabVIEW Features book on the Contents tab of the LabVIEW Help for a list of unsupported LabVIEW features for each RTOS.

Installation Instructions

You can install all of your LabVIEW products, including the LabVIEW Real-Time Module, using the LabVIEW Platform DVDs. You can find installation and activation instructions for the Real-Time Module in the following locations:

  • LabVIEW Real-Time Module Release and Upgrade Notes, which are available in your LabVIEW Real-Time Module software kit or online at
  • LabVIEW 2012 Installation Guide, which is available in your LabVIEW software kit.
  • LabVIEW 2012 Service Pack 1 Platform DVDs Readme, which is available on the top-level of LabVIEW Platform DVD 1.

To request additional LabVIEW Platform DVDs, refer to the National Instruments website.

Installing and Using Japanese and Simplified Chinese Languages on an RT Target

After you install the Real-Time Module on your development computer, you can complete the following steps to install and use Japanese and Simplified Chinese languages on an RT target.

  1. Use the LabVIEW Real-Time Software Wizard in NI Measurement & Automation Explorer to install the Language Support for Japanese or Language Support for Simplified Chinese software component on the RT target. Refer to the NI Measurement & Automation Explorer Help for information about the LabVIEW Real-Time Software Wizard.
  2. Open the System Settings tab and select Japanese or Simplified Chinese as the Locale.

Accessing the Help

Refer to the LabVIEW Help, accessible by selecting Help»LabVIEW Help from LabVIEW, for information about the LabVIEW 2012 SP1 Real-Time Module.

Finding Examples

Select Help»Find Examples from LabVIEW to launch the NI Example Finder. Examples for the LabVIEW Real-Time Module are located in the labview\examples\Real-Time directory. You can modify an example VI to fit an application, or you can copy and paste from one or more examples into a VI that you create.

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, refer to the following KnowledgeBase articles:

How to Use NI Software with Microsoft Windows 8

When you install National Instruments software on Microsoft Windows 8, you will notice a few additional tiles on the Start screen, including shortcuts to NI application software products such as NI LabVIEW, Measurement & Automation Explorer (MAX), and the new NI Launcher.

Using NI Launcher

NI Launcher helps you find and launch installed NI products. It provides you with a method of finding NI products similar to the Start menu in previous versions of Microsoft Windows. To use NI Launcher, click the NI Launcher tile on the Start screen. NI Launcher launches the desktop and opens a menu containing a list of NI products. Click any NI product to launch it.

Note  Unlike previous versions of Microsoft Windows, MAX does not appear as a desktop shortcut. You can launch MAX either from the Start screen or from within NI Launcher.

Pinning Frequently Used Applications

For convenience, you can pin your most-used NI applications, such as MAX, to either the Start screen or the Taskbar on the desktop, as necessary:

Current ApplicationIcon LocationPin to Action
Windows 8 DesktopDesktop TaskbarRight-click application and select Pin to Taskbar
Windows 8 Desktop Start screenRight-click application and select Pin to Start
Windows 8 Start screenDesktop TaskbarRight-click application and select Pin to taskbar from the menu bar on the bottom of the screen

Finding All Programs

If you want to find a particular application or related files, such as documentation files, from the Start screen, you can access all installed files by right-clicking anywhere on the Start screen and selecting All apps. A list of all installed software and related files appears, in alphabetical order by creator or type.
