where is cvi_lvrt.dll

[hrobitaille]

I am trying a third party software which include a VI library and a DLL.
On my request, the DLL has been built with LabWindows/CVI for LabVIEW Real-Time.
But now if I try to use the VI examples (which call the DLL), when I specify the path to the new DLL, I have an error "Secondary DLL could not be found", even I run LabVIEW on the host system.

Looking at the DLL, we can see, in the importation table, reference to 3 DLL : USER32.DLL, KERNEL32.DLL and cvi_lvrt.dll.
Where can we found the cvi_lvrt DLL and where must we install it ?

Thanks for your help

Hello,

The cvi_lvrt.dll is a file that ships with LabWindows/CVI - whoever wrote the driver DLL for you should be able to provide a copy of this file. The DLL is a support file that should be placed in your ~\National Instruments\LabVIEW\ directory. If you can not get it from them, there is an example of calling a DLL built in CVI if you follow this link - the example itself is irrelevant but part of that distribution includes the cvi_rt.dll so you could just download it from there.
