Issue Details

  • I have a VI that uses NI-DAQmx driver. The VI works fine as a VI, but when I compile it as an executable and run it on the same computer, I receive the error message Resource Not Found: nilvaiu.dll.
  • I just installed the LabVIEW Run-Time and my DAQmx executable on a new computer and it fails to run saying that is is missing the nilvaiu.dll.
  • When I try to open a VI that uses NI DAQ-drivers LV asks for nilvaiu.dll. However I cannot find it.


There are five recommendations on how to solve it:  If those suggestions does not help, please contact National Instruments .

Additional Information

NI-DAQmx LabVIEW uses function calls from a nilvaiu.dll.
