Known Issues

You can access the software and documentation known issues list online. Refer to the National Instruments website for an up-to-date list of known issues in LabVIEW 2012.

LabVIEW 2012 (64-bit)

When run on Windows (64-bit), LabVIEW 2012 (64-bit) provides access to more memory than a 32-bit operating system or a 32-bit application can provide. LabVIEW 2012 (64-bit) includes nearly all of the development environment features of LabVIEW 2012 (32-bit).

Refer to the National Instruments website for information about obtaining a copy of LabVIEW 2012 (64-bit).

Supported Hardware

LabVIEW 2012 (64-bit) supports many hardware devices. Refer to the National Instruments website for information about drivers compatible with LabVIEW 2012 (64-bit). For GPIB devices, you must use at least NI-488.2 2.6 for Windows. Refer to the specific hardware documentation for more information about compatibility with LabVIEW 2012 (64-bit).

Supported Modules

LabVIEW 2012 (64-bit) supports only the NI Vision Development Module. Refer to the Vision Development Module documentation for more information. No additional modules support LabVIEW 2012 (64-bit).

Additions to the LabVIEW Help

The following list contains additional changes to LabVIEW that are not included in the LabVIEW Help, the LabVIEW Upgrade Notes, or both:

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.
