Archived: Traditional DAQ Palette Does Not Appear In LabVIEW

This document has been archived and is no longer updated by National Instruments

Note: This page is about NI-DAQ also known as Traditional NI-DAQ (Legacy). NI-DAQmx replaced Traditional NI-DAQ (Legacy) in 2003. NI strongly recommends using NI-DAQmx for new designs and migrating existing Traditional NI-DAQ (Legacy) applications to NI-DAQmx. Please review the Getting Started with NI-DAQmx guide for more information on migration.


Primary Software:
Primary Software Version: 4.6.1
Primary Software Fixed Version: N/A
Secondary Software: N/A

Problem:
I recently upgraded LabVIEW versions or have multiple versions of LabVIEW installed and chose to include the Traditional NI-DAQ (Legacy) driver during the installation.  However, I do not see the Traditional DAQ Subpalette on the Functions Palette and I cannot access the example programs from the NI Example Finder.  I tried to repair the driver, but this did not help.  How do I correct this problem?

Solution:
This problem occurs when you have installed the Traditional NI-DAQ (Legacy) driver with a previous version of LabVIEW and you do not uninstall it before the LabVIEW upgrade is performed.  Because the driver is detected as already being installed when the upgrade is performed, no support for the new installation of LabVIEW is installed.  This is a known issue with the Traditional NI-DAQ (Legacy) driver.

There are two solutions to this problem depending on your  use case:

To use Traditional NI-DAQ (Legacy) with only the latest version of LabVIEW

  1. Uninstall Traditional NI-DAQ (Legacy) via the Windows Control Panel Add or Remove Programs dialog.  You may be required to remove other drivers that are dependent upon Traditional NI-DAQ.  You can reinstall these drivers after step 2.
  2. Reinstall Traditional NI-DAQ (Legacy) using the Device Driver CD/DVD provided with the newest version of LabVIEW.  You can also download the driver from our website at Drivers and Updates: Traditional NI-DAQ (Legacy) 7.4.4 - Windows 2000/XP (linked below). This will install Traditional NI-DAQ support to the latest version of LabVIEW installed on the machine.
  3. Reinstall any drivers that were dependent on Traditional NI-DAQ.

To use Traditional NI-DAQ (Legacy) with multiple versions of LabVIEW

Copy over the following folders from the most recent version of LabVIEW to the other LabVIEW version folders. [LVDIR] indicates the folder of the latest LabVIEW version, such as C:\Program Files\National Instruments\LabVIEW 8.6.;
    • [LVDIR]\vi.lib\daq
    • [LVDIR]\examples\daq
    • [LVDIR]\help\lvdaq.chm
    • [LVDIR]\menus\default\daq
Notes: The Traditional NI-DAQ (Legacy) API is mass-compiled in LabVIEW 7.0. This will not affect the functionality of your VIs. However, LabVIEW will prompt you to save the Traditional NI-DAQ (Legacy) subVIs if your LabVIEW version is greater than 7.0. To avoid the prompts, mass-compile the folders referenced above. For information on mass-compiling, see the related links below. If you require Traditional NI-DAQ (Legacy) support for versions of LabVIEW earlier than 7.0, you need an earlier version of Traditional NI-DAQ (Legacy).  These can be downloaded from ni.com/support.

One caveat: If you open and save any examples or create any VIs in your latest version of LabVIEW you will not be able to use the VI's in a previous version. It is very important to copy the folders before saving the VI's.
