Cant find nilvaiu.dll

[kaawn]

Hi everyone,

I recently copied a project over to a computer that runs windows 10 from a computer that runs windows xp. They both use Labview 8.0. However, when I tried to run the program, it gave me an error saying that the nilvaiu.dll cannot be found. I check the system32 folder and this library does not exist there, but when I checked the vi.llb folder in national instrument, DAQmx was listed as a library. Is it possible that the DAQmx version is different? If not what is causing this? I believe if I install NI DAQmx 8.7.1, it could solve my problem, but does anyone know how to download that driver? I cannot find that driver anywhere in the internet? Is there a link to NI legacy drivers?

Thanks,

Kaawn

The "oldest" form of LabVIEW that is supposed to work with Windows 10 is LabVIEW 2015.  If you are using LabVIEW 8, you should "migrate" to a more current version of LabVIEW, which will certainly involve different DAQmx support files.

Hi Bob,

For some reason LabVIEW 8.0 was working perfectly in windows 10 for me, or at least that's what I thought. What I did not know was that some drivers do not get installed properly if they are not compatible with the OS, and that was causing the problem. I had another computer sitting around that had XP on it, I installed Labview in that, and it works now. 

Thanks for the help,

Kaawn
