Unlike the LabVIEW Development Environment , the Runtime Engine does not provide tools for editing or debugging code; it is purely an execution layer. Compatibility and System Requirements
Version 6.1 was designed for older environments like Windows XP, 2000, and early versions of Linux or Mac OS. It is generally not supported on Windows 10 or 11, though some users attempt to run it using compatibility modes.
LabVIEW applications strictly require a Runtime Engine version that matches the version they were built in. An executable created in LabVIEW 6.1 cannot run on the 2026 Q1 Runtime.
