Automating the Installation of NI Products
Using NI Software with Microsoft Windows 10
Using NI Software with Microsoft Windows 8.1
The LabVIEW DSC Module extends the LabVIEW graphical development environment with additional functionality for the rapid development of distributed measurement, control, and high-channel-count monitoring applications. The DSC Module enhances the LabVIEW shared variable, supports logging data to the Citadel and relational databases, enhances the Historical Data Viewer and the NI Distributed System Manager, and provides tools for graphing historical or real-time trends, enhancing the security of front panels, and writing custom I/O servers.
In addition to the system requirements for the LabVIEW Development System, the DSC Module has the following requirements:
Refer to the LabVIEW Readme for additional system requirements and supported operating systems for LabVIEW 2019.
Note The DSC Module is compatible with LabVIEW (32-bit) only. Therefore, you must have LabVIEW (32-bit) installed even if you use a 64-bit OS.
The DSC Module supports the following operating systems:
1 NI software installs VC2015 Runtime and .NET 4.6.2. Windows 8.1 and Windows Server 2012 R2 require Microsoft updates to support these items. Refer to Microsoft KB2919442 and KB2919355 for more information about how to install these updates.
2 NI software is signed with a SHA-256 certificate. Windows 7 SP1, Windows Embedded Standard 7 SP1, and Windows Server 2008 R2 SP1 require Microsoft updates to support SHA-256. Refer to Microsoft KB3033929 for more information about how to install this security update.
Note
NI automates software installation using NI Package Manager. 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 also install the DSC Module using the LabVIEW 2019 Platform media. To request additional LabVIEW Platform media, refer to the NI website.
Note
The DSC Module relies on licensing activation. When the evaluation period expires, you must activate a valid DSC Module license to continue using the DSC Module.
The NI OPC Servers application installed with the DSC Module provides a temporary license for a two-hour evaluation period. You must activate a valid license to continue using the NI OPC Servers application after the evaluation period expires.

Refer to the LabVIEW Help, accessible by selecting Help»LabVIEW Help, for information about the DSC Module.
Select Help»Find Examples from LabVIEW to launch the NI Example Finder. LabVIEW examples for the DSC Module are located in the labview\examples\lvdsc 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.
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 the following KnowledgeBase articles:
Microsoft Windows 10 is the latest version of the Windows operating system and features significant changes compared to previous versions.
