It is common and perfectly fine to have several different versions (e.g., 8.5.1, 2013, 2020) installed on the same computer. This allows you to run applications built with different LabVIEW versions. Each version resides in its own directory and does not interfere with the others.
If you're writing a report or documentation on why this specific version is needed, here are the essentials:
The term "LabVIEW Runtime Engine 8.5.1" refers to a legacy version of the National Instruments (NI) software environment required to run executables built in LabVIEW 8.5.1. The addition of "hot" in the search query typically suggests a user looking for a "popular" link or a "hotfix," though in this context, it most likely refers to a high-demand download.

This is common due to missing legacy components. The installer may fail due to a missing . Try installing the Visual C++ 2005 Redistributable first. If that fails, run the installer in Windows 7 Compatibility Mode (right-click → Properties → Compatibility → Run this program in compatibility mode for: Windows 7) and as an administrator.
The LabVIEW Run-Time Engine (RTE) acts as a bridge between a LabVIEW executable (.exe) and the operating system. Unlike a standard source code file (.vi), a compiled application requires a set of shared libraries and background processes provided by the RTE to interpret code and manage hardware communication. It is important to note that the RTE is version-specific; an application built in LabVIEW 8.5.1 must use the 8.5.1 Run-Time Engine to function correctly. Key Features and Compatibility of Version 8.5.1
If you downloaded a .zip file, extract it to a temporary folder.
You should use this runtime if a specific application's documentation calls for it. While a version check error message during installation or execution will also point you to the exact LVRTE version required, the key point to remember is that runtime engine versions are generally not forward or backward compatible: .
: Historically, NI provided direct links for version 8.5.1 via FTP or HTTP for specific community distributions.
