Deploying Vision Applications

Deployment refers to developing an application so that it can be distributed, or deployed, on a different computer than the one on which the application was developed. The NI Vision Development Module provides everything you need to deploy custom NI Vision applications to target computers. The NI Vision Development Module provides the following options:

• The ability to create NI Vision Run-Time Engine installers, which integrate with the LabVIEW Application Builder, applications built in LabWindows/CVI, or a custom installer.
• The ability to install the NI Vision Run-Time Engine directly from the Vision Development Module CD.
• One NI Vision Run-Time License, which allows you to install a custom application on a single machine.
  

The NI Vision Development Module installer contains the run-time engine installer for NI Vision. The run-time engine installer is installed at \Run-Time Engine, where is the location to which the NI Vision Development Module is installed. Visit the Drivers and Updates section of ni.com to download software upgrades for NI Vision and the NI Vision Run-Time installers.

Purchasing NI Vision Deployment Licenses

You must purchase an NI Vision Run-Time License (part number 778044-03) for each target machine onto which you want to install your custom NI Vision application, even if you install the NI Vision Run-Time Engine directly from the NI Vision Development Module CD. The NI Vision Development Module CD ships with one run-time license. Contact a National Instruments sales representative or visit ni.com to purchase additional run-time licenses.

Note: Additional NI Vision Run-Time Licenses do not include a CD. To install additional licenses, use the original NI Vision Development Module CD and the serial number provided by National Instruments.

Using the NI Vision Run-Time Engine

You can call the NI Vision Run-Time Engine installer from the application installer. If you create the application installer with the LabVIEW Application Builder or with LabWindows/CVI, you can direct the installer to call the NI Vision Run-Time Engine installer.

Refer to the LabVIEW Help for more information about the LabVIEW Application Builder. Refer to the NI LabWindows/CVI Help for more information about building and distributing LabWindows/CVI applications.

You can also direct a custom application installer to call the NI Vision Run-Time Engine installer. Refer to the documentation that came with the installer software to learn how to call executables from the custom installer. If you are using a custom installer, call the NI Vision Run-Time Engine installer at the end of the installation procedure because the installer may require the system to be restarted.

To use the NI Vision Run-Time Engine installer, you must add /qn as a command line argument to the run-time engine installer. For example, enter \Run-Time Engine\vision2012rte.exe /qn to run the NI Vision Run-Time Engine installer, where is the location to which NI Vision is installed.

Distributing LabVIEW Applications

The NI Vision Run-Time Engine installer does not install LabVIEW VIs. If you use the LabVIEW Application Builder to create an application (EXE) or dynamic link library (DLL), the Application Builder automatically includes the VIs used by the application. If you distribute a VI, you must include all subVIs that comprise the top-level VI. You must include the appropriate LabVIEW Run-Time Engine as part of the installation.

Refer to the LabVIEW Help for more information about viewing the hierarchy of VIs and for more information about using the LabVIEW Run-Time Engine.

Distributing LabWindows/CVI Applications

In addition to including the NI Vision Run-Time Engine with the installer, you must include the appropriate LabWindows/CVI Run-Time Engine. Refer to the NI LabWindows/CVI Help for more information about creating an executable, creating a dynamic link library, and distributing applications.

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:

• For more information on silent installations of individual NI products, refer to KB 4CJDP38M, Automating the Installation of a Single Installer.
• For more information on silent installations of suited NI products, such as NI Developer Suite, refer to KB 4GGGDQH0, Automating 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 National Instruments Installer?.
  

Known Issues

You can access the software and documentation known issues list online. Refer to the National Instruments Web site for an up-to-date list of known issues in the NI Vision Development Module.
