Issue Details

I am uncertain about the difference between LabVIEW Run-Time and Real-Time. Which one am I supposed to use for what? Do I need both of them installed?


LabVIEW Run-Time (for running stand-alone executables)

The LabVIEW Run-Time Engine must be installed on any system where you plan to run compiled code such as stand-alone executables or shared libraries built with the LabVIEW Application Builder. The major version of the LabVIEW Run-Time Engine must match the major version of the LabVIEW Development Environment that was used to create the executable. 

LabVIEW Real-Time (for working with real-time targets)

The LabVIEW Real-Time Module is an add-on component for the LabVIEW development system that you can use to create and debug applications that run on stand-alone embedded hardware targets. With the LabVIEW Real-Time Module, you can develop applications for all NI real-time hardware targets including CompactRIO, stand-alone CompactDAQ, PXI controllers, NI compact vision systems, and standard desktop PCs. The LabVIEW Real-Time Module works with NI hardware running either the Phar Lap ETS, VxWorks, or NI Linux Real-Time OS.
