As of 2021 and beyond, finding this legacy version requires navigating NI’s archived support systems:

Official NI Download Page: The most reliable way is through the NI LabVIEW Runtime Download page. You will need to log in and may need an active service agreement to access older archived versions.

NI Archive/FTP: Community members often point to NI’s legacy FTP or download servers for these specific files, such as download.ni.com.

NI Package Manager (NIPM): While NIPM is the modern standard for installing NI software, very old versions like 8.5.1 are often not listed. If it isn't visible, you must contact NI Support to request the specific legacy installer. Key Compatibility and Installation Notes

Operating System Support: LabVIEW 8.5.1 was originally designed for Windows Vista and XP. It does not officially support Windows 10 or 11. While it may "work" on 32-bit versions of modern OSs, NI recommends migrating older code to a newer LabVIEW version (like LabVIEW 2021) for stable performance on modern hardware.

Bitness Matters: Ensure you download the version (32-bit or 64-bit) that matches the bitness of the original application. On 64-bit systems, you can install both 32-bit and 64-bit versions of the RTE side-by-side.

Side-by-Side Installation: Multiple versions of the LabVIEW Run-Time Engine can coexist on one machine as long as the major version numbers differ (e.g., you can have 8.5.1 and 2021 installed simultaneously).

Web Browser Plug-in: The standard RTE download usually includes the Web Browser Plug-in for viewing Remote Front Panels in a browser.
