DAQ Assistant Missing, Not Showing Up, or Not Initializing Correctly in LabVIEW

Issue Details

• I have already installed LabVIEW, and the DAQ Assistant Express VI is missing or not showing up in my Measurement I/O functions palette, or when I use search.
• I just installed NI-DAQmx and LabVIEW, but DAQ functions, like DAQ Assistant, are not available in LabVIEW. However, I can create a task in NI MAX. What's wrong with LabVIEW?
• I am able to see the DAQ Assistant VI, but I am having issues when trying to load it, as it does not initialize correctly when I place it in LabVIEW.

Solution

The DAQ Assistant is part of the NI-DAQmx DAQ hardware driver and is not included with the LabVIEW download. Go through the following checks to ensure that DAQmx is downloaded and compatible with your system.

If you are having issues locating the DAQ Assistant VI

Follow these troubleshooting steps to resolve the issue:

• Ensure compatibility for your Operating System (OS), LabVIEW, and NI-DAQmx versions by checking the following charts:
  • LabVIEW and Microsoft Windows Compatibility
  • NI-DAQmx and LabVIEW Compatibility
• Ensure that the Installation Order for Multiple NI Software Products is followed. LabVIEW must be installed first and then NI-DAQmx must be done after.
  • If the installation was in the incorrect order, repairing or force reinstalling the DAQmx driver will fix the order.
• Upgrade to the newest DAQmx driver the LabVIEW version can support
• Try Repairing the software using NIPM or Forcing the Reinstallation of DAQmx
  • When repairing the driver, make sure you are selecting to include NI-DAQmx Support for your release of LabVIEW.  As an example you may need to ensure you have installed NI-DAQmx Support for LabVIEW 2021 (32-bit).

Note: If you are still unable to locate the DAQ Assistant, follow the steps in the article Missing Icons on Functions or Control Palette . 

If you are seeing the DAQ Assistant VI in LabVIEW but you are having issues initializing or loading it.

• Try Repairing the software Using NIPM or Forcing the Reinstallation of DAQmx since this can be directly caused by a corruption of the software.
