Issue Details

I recently upgraded or updated to a newer version of LabVIEW. I either previously had NI-DAQmx installed but it no longer works, or I ran a NI-DAQmx installer as part of the setup and am having issues.  I'm able to see my DAQ device or module in NI MAX and can run a self-test and read values using the test panels.  I am running into one or more of the following problems:
  • Since installing LabVIEW, the functions and subVI’s from the DAQmx palette are missing, not available, not showing up, aren’t working, are broken, or I am being prompted to locate them after searching.
  • I am getting an error saying that the DAQmx driver was not found.

Why can’t LabVIEW find my DAQmx functions and subVI’s? Do I need to install a compatible or supported version to meet new requirements?


There are two common causes of problems after a LabVIEW upgrade when using NI-DAQmx:
  • Incompatibility between the Operating System (OS), LabVIEW, NI-DAQmx, and the hardware devices or modules being used.
  • Failing to install or repair NI-DAQmx after the LabVIEW installation.

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.
