Labview Runtime engine

[liyue]

A weird thing happened here: We have an old PC installed with a full version labview software. An engineer developed a Labview GUI. We can use that GUI to communicate with our controller board using RS232 port.

Now, we want to use that labview GUI on another PC. I think we do not need to install a labview software in the new PC but a labview runtime engine. Okay, then I downloaded and installed the RUNTIME engine 8.5. 

However, the GUI failed to set up communication with my controller board....GUI still can be opened but no communication with my board. No error messages as well....

Anybody can give me some tips?

Thanks a lot!

If your application uses the NI-VISA functions then you will need to install VISA Runtime Engine on target PC as well.  Easiest way is to create an installer that includes the LV Runtime Engine and the VISA Runtime Engine.
