As the Traditional NI-DAQ driver software is not supported on Windows Vista or Windows 7, the following CAN/DAQ synchronization VIs are not available on Windows Vista or Windows 7:
NI-CAN provides support for CANdb network files created using the Vector CANdb or CANdb++ editor. You can use the information from the CANdb file in Measurement & Automation Explorer (MAX) or with the NI-CAN Channel API. For more information, refer to the Using the Channel API chapter in the NI-CAN Hardware and Software Manual.
NI-CAN supports CANdb network files created using the CAN module of Vector products. NI-CAN does not provide complete support of CANdb files created using modules for higher-layer CAN protocols, such as J1939, ISO11783, or NMEA2000. To view the set of features supported for these modules, import the CANdb file into MAX. NI-CAN displays an error dialog for any unsupported object and displays those objects with a red mark. For example, the J1939 protocol for multiframe messages (greater than 8 bytes) is not supported in the current version of NI-CAN.
NI-CAN 2.4 (or newer) includes several new Frame API attributes. If you have a LabVIEW VI written for an earlier version of NI-CAN, upgrading to NI-CAN 2.4 (or newer) will not automatically update constants or controls for the AttrId input. To use the new attributes, replace your older constants and controls using the AttrId input of the updated NI-CAN VIs.
If you do not want to use new Frame API attributes, you can continue to use the older constants and controls for compatibility.
This issue does not apply to the Channel API for LabVIEW. Because the Get/Set Property functions are provided as polymorphic VIs, they are automatically updated.
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:
Microsoft Windows 10 is the latest version of the Windows operating system and features significant changes compared to previous versions. Windows 10 introduces several new capabilities and also combines features from both Windows 7 and Windows 8. For more information about NI support for Windows 10, visit ni.com/windows10.
When you install NI software on Microsoft Windows 8.1, 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. For more information about NI support for Windows 8.1, visit ni.com/windows8.
