Issue Details

I am using LabWindows/CVI and NI-DAQmx to build an executable.  It has worked previously, but now returns a Non-Fatal Run-Time Error.

The message reads: 
Function DAQmxCreateTask: (return value == -200398 [0xfffcf132]), Unable to find function in NI-DAQmx dynamic link library (DLL) NICAIU.DLL.

The DLL exists on your computer, but the version is incorrect. Install the correct version of the DLL on your machine.

The error I see looks like this: 

Or this:


This was a known issue affecting non-current versions of DAQmx. Please upgrade to the latest version of NI-DAQmx to resolve this issue. 


Additional Information

  • This error can occur when unused or empty functions are removed between DAQmx versions.  Updating to more recent versions resolves this error by replacing references to those functions.
  • This issue is specific to how LabWindows/CVI loads the DAQmx C DLL and does not affect other application development environments such as LabVIEW.
