Instead of bloating every single executable by bundling these resources, NI uses the Run-Time Engine.
When an engineer builds an application in LabVIEW, the primary development environment translates graphical code (known as virtual instruments, or VIs) into machine-level instructions. However, the resulting executable does not contain all the subroutines, UI rendering code, memory allocation structures, or math libraries required to run on its own.
Version 8.5.1 of the Run-Time Engine is specifically designed for applications built with LabVIEW 8.5 or 8.5.1. You may only use version 8.5.1 of the Run-Time Engine to run these particular executables or view LabVIEW Remote Panels built with those specific LabVIEW versions.

Version 8.5.1 is often a "Goldilocks" version for specific hardware drivers. Many PCI-GPIB cards, legacy PXI controllers, and third-party oscilloscope drivers from Agilent (now Keysight) or Tektronix were compiled against this exact runtime. A mismatch—using version 8.6 or 8.2—often results in the dreaded "VI version mismatch" error.
In the fast-paced world of software, where updates are forced annually and backward compatibility is often an afterthought, industrial automation tells a different story. Deep within the control cabinets of manufacturing plants, university laboratories, and legacy aerospace test rigs, a specific version of National Instruments’ software hums along quietly: .
Add /log c:\temp\install.log for debugging. Instead of bloating every single executable by bundling
This error, stating something like "COCKPIT requires version 8.5.1," clearly indicates a version mismatch or missing installation.
Note that most 8.5.1 applications are 32-bit, so you should install the 32-bit runtime engine even on a 64-bit operating system. Common Issues & Troubleshooting

Lin’s fingers flew. Five minutes later, she let out a low whistle. “You are not going to believe this. Someone archived a folder called NI_RTE_8.5.1_FINAL . It’s a 78-megabyte .exe. The checksum matches an original NI distribution from August 2007.”
