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 2015.
When run on Windows (64-bit), LabVIEW 2015 (64-bit) provides access to more memory than a 32-bit operating system or a 32-bit application can provide. LabVIEW 2015 (64-bit) includes nearly all of the development environment features of LabVIEW 2015 (32-bit).
Refer to the National Instruments website for information about obtaining a copy of LabVIEW 2015 (64-bit).
LabVIEW 2015 (64-bit) supports many hardware devices. Refer to the National Instruments website for information about drivers compatible with LabVIEW 2015 (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 2015 (64-bit).
LabVIEW 2015 (64-bit) supports only the NI Vision Development Module. Refer to the Vision Development Module documentation for more information. No additional modules support LabVIEW 2015 (64-bit).

Refer to the LabVIEW Help, accessible by selecting Help»LabVIEW Help from LabVIEW, for information about LabVIEW 2015.
Select Help»Find Examples from LabVIEW to launch the NI Example Finder. 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. 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 about automating the installation of NI products, refer to the following KnowledgeBase articles:
When you install National Instruments software on Microsoft Windows 8.x, you will notice a few additional tiles in the Apps view, including shortcuts to NI application software products such as NI LabVIEW, Measurement & Automation Explorer (NI MAX), and 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 in the Apps view. NI Launcher launches the desktop and opens a menu containing a list of NI products. Click any NI product to launch it.
Note NI MAX does not appear as a desktop shortcut when installed on Microsoft Windows 8.x. You can launch NI MAX either from the Apps view or from within NI Launcher.
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 Application | Icon Location | Pin to Action |
|---|---|---|
| Windows 8.x Desktop | Desktop Taskbar | Right-click application and select Pin to Taskbar |
| Windows 8.x Desktop | Start screen | Right-click application and select Pin to Start |
| Windows 8.x Start screen | Desktop Taskbar | Right-click application and select Pin to taskbar from the menu bar on the bottom of the screen |
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 from the Apps view. To get to the Apps view, right-click anywhere on the Start screen and select All apps (Windows 8.0) or click the down arrow on the bottom left of the screen (Windows 8.1).
For more information about NI support for Windows 8.x, visit ni.com/windows8.
LabVIEW will drop support for Microsoft Windows Vista, Windows XP, and Windows Server 2003 as of July 1, 2016. Versions of LabVIEW that ship after July 1, 2016 will not install or run on Windows Vista, Windows XP, or Windows Server 2003.
