Unlike newer runtimes, the LabVIEW 6.1 Exclusive engine cannot run VIs built with LabVIEW 6.0 or 5.x. It is strictly for 6.1 executables. Conversely, newer runtimes (e.g., 8.x or later) cannot run 6.1 executables. This exclusivity forces strict version matching: your .exe and your RTE must be binary-identical.

In early versions of LabVIEW, including 6.1, the Run-Time Engine version had to exactly match

LabVIEW, a graphical programming environment developed by National Instruments (NI), is widely used for designing, prototyping, and deploying automated test and measurement systems. The LabVIEW Runtime Engine plays a crucial role in executing LabVIEW applications on systems where LabVIEW itself is not installed. This blog post aims to provide an in-depth understanding of the LabVIEW Runtime Engine 6.1, specifically the "exclusive" version, its significance, and its applications.
