It often depends on legacy Visual C++ runtimes (specifically Visual Studio 2005/2003 runtimes). On very new processors or Windows builds, the installer may fail to launch. This is a known issue with the 8.5.1 installer on modern hardware (e.g., Intel NUCs) because the setup executable itself has a dependency on older Microsoft C++ libraries that may not be present by default on a fresh Windows 10/11 installation.
The National Instruments (NI) LabVIEW 2021 Runtime Engine (8.5.1 equivalent or specific architecture builds) is a critical software component required to execute pre-compiled LabVIEW applications (.exe files) without requiring the full, paid LabVIEW development environment installed on the target machine. labview runtime engine 85 1 download 2021
