Can’t Find NI-DAQmx Functions after LabVIEW or NI-DAQmx Install

Issue Details

I recently installed LabVIEW or updated my NI-DAQmx version. I may already be able to see my DAQ device or module in Windows Device Manager or NI Measurement & Automation Explorer (MAX) under Devices and Interfaces.

I am experiencing one or more of the following problems:
  • DAQmx LabVIEW subVI icons do not show up, aren’t visible or don’t appear in my LabVIEW Measurement I/O functions palette. One example of this is shown below:
  • DAQmx .mnu file is missing or DAQmx folder is missing from \vi. lib .
  • DAQmx functions and libraries show up in one version of LabVIEW, but not another. Similarly, they show up 32-bit LabVIEW, but not in 64-bit or vice versa.
  • I am getting a broken run arrow or searching for DAQmx subVI’s when opening a VI or trying to run DAQmx calls.
  • I installed DAQmx using the NI Package Manager. However, I am missing DAQmx VIs in LabVIEW.

Why can’t LabVIEW find my DAQmx palette, functions and subVI’s or run my code? Is my installation corrupted or is there a bug in the installer?


There are two common causes of problems after a LabVIEW upgrade when using NI-DAQmx:
Upgrading or Downgrading LabVIEW with NI-DAQmx explains how to verify the software and driver versions needed for your system, how to upgrade or downgrade LabVIEW properly, and additional troubleshooting steps to perform after installation.
