Here is the brutal truth: National Instruments (NI) prioritizes security and support for current versions. As of 2023, NI does not actively promote the download of LabVIEW 8.5.1 via their main marketing pages. The official NI website now hosts versions 2020, 2021, 2023, and beyond.
However, "legacy" does not mean "lost." National Instruments maintains a Legacy Software Download repository, though it requires authentication.

Step-by-Step:
www.ni.com > Support > Downloads.LVRTE851.exe (Standard Windows)LVRTE851_Update.exe (If you already have a base install)The "Serial Number" Myth: You do not need a serial number for the Runtime Engine. It is freeware. However, the NI website may ask for a serial to prove you are an engineer; you can usually bypass this by selecting "Evaluation" or "Runtime Distribution."
Cause: The Visual C++ 2003 Redistributable is missing.
Fix: Download vcredist_x86.exe for Visual Studio 2003 (VC7). Install before the LabVIEW RTE.
