LabVIEW Run-Time cannot find nilvaiu.dll

[Arlen]

It wants a series of DAQmx vi's that for some reason aren't in either the AppBuilder files or the LVRT installation.

The app is built to attempt to read from DAQ eqipment, but if there is none it defaults to a simulation.

You probably need to install NI-DAQ on that target machine, even if there is no DAQ hardware.

(Here's the link to NI-DAQ 7.1).

Thanks for your help. Problem solved !!

I followed your advice and compiled an EXE to test the system. When I ran it on an LVRT PC I found it was looking for several other dll's. Upon investigation I realised the required dll's are all part of NI-DAQ (mx). Once I installed the NI-DAQ drivers, everything worked, including the original dll.

I assumed the DAQmx VIs that were included in the build list (for the dll/exe) eliminated the need to install NI-DAQ on the LVRT PC. My mistake.

Thanks heaps for your advice and help.
