Often, older runtimes are stored in the ftp.ni.com directory structure.
For those who successfully install it, the 8.5.1 engine offers a snapshot of a turning point in graphical programming. It introduced features that were revolutionary at the time but are now standard:
Right-click the downloaded installer file and select Run as Administrator to grant the necessary registry modification privileges.
National Instruments (NI) hosts these files on their official support servers. Note that accessing legacy software on the main NI website often requires a and sometimes an active service agreement . Primary Download Page: LabVIEW Runtime Download - NI

If the application was built as a 32-bit executable (most common for 8.5.1), you must install the 32-bit run-time engine, even on a 64-bit Windows machine.
Note that the RTE does not always include hardware drivers (like NI-DAQmx or NI-VISA). If your application interacts with physical hardware, those drivers must be downloaded and installed separately. Troubleshooting Common Issues
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. Often, older runtimes are stored in the ftp
Download and install the specific driver runtime versions that match the deployment date of LabVIEW 8.5.1. Side-by-Side Installation Issues
For modern systems, try right-clicking the installer and selecting "Troubleshoot compatibility." Run the installer as if you were on Windows XP (Service Pack 3).
The Ultimate Guide to LabVIEW Runtime Engine 8.5.1: Downloads, Installation, and Troubleshooting
If prompted, choose a temporary directory to extract the installation files (e.g., C:\National Instruments Downloads ). National Instruments (NI) hosts these files on their

I can also help you determine if your are compatible with this legacy version.
Visiting such a link may present you with an index of the directory on NI's servers. From there, you can find the appropriate installer file, which is typically a .exe file. For LabVIEW 8.5, the installer was named LabVIEW85RuntimeEngineFull.exe . For version 8.5.1, the filename may be similar, such as LVRT851std.exe or a similar variant. This method requires a bit of manual navigation but is considered the safest approach as the files come directly from NI.
Right-click the setup.exe file inside the unzipped installation folder. Select and navigate to the Compatibility tab.
