Where to find nilvaiu.dll?

[mrostyn]

I am trying to run a DAQ-enabled .exe file on a LVRT computer. When I try running my .exe file, it cannot find a few .dll files, starting with "nilvaiu.dll". I have seen other boards indicate that this can be solved by installing the appropriate NI-DAQ drivers. I have since installed NI-DAQmx 16.1 on the LVRT computer, and the .dll files still cannot be found. Would I need to manually find these in the installed NI-DAQ drivers found in Program Files? If so, what is their location?

Check to make sure that Windows, DAQmx and the runtime are all compatible.

Hi mrostyn,

Yeah, as aputman suggested, make sure that all of the versions are compatible. Here's some resources to verify this:

• NI-DAQmx and LabVIEW Compatibility
• NI Hardware and OS Compatibility

If you want to verify those files are correctly installed, you should find them in the following locations:

• C:\Windows\System32\nilvaiu.dll
• C:\Windows\SysWOW64\nilvaiu.dll

Finally, do make sure that you have enabled the Real-Time support for DAQmx when installing. If you have not, check out this article for more information.
