Labview Runtime Engine 61 Exclusive -

“Exclusive” in runtime engine usage can mean one or more of the following:

The "Exclusive" installer for 6.1 often uninstalled previous runtimes during setup. This was a massive pain point for integrators running multiple legacy applications but a necessity for conflict-free operation on Windows 2000 or NT4 machines.

Some older LabVIEW executables (especially those built with the Application Builder for 6.1) would register the runtime as the default handler for .vi or .vit files and block other runtime versions from being installed or used simultaneously. This is a misbehavior of the installer, not an official feature. labview runtime engine 61 exclusive

Automotive part manufacturers often buy test systems designed to last 15-20 years. If a company purchased a dynamometer controller built with LabVIEW 6.1 in 2002, that system is still running on a ruggedized PC using Windows 2000. Replacing the LabVIEW application would cost $200,000+ in recertification. Instead, they keep the LabVIEW Runtime Engine 6.1 Exclusive on a ghosted hard drive.

The runtime engine is configured so that only one LabVIEW application can use it at a time. If a second LabVIEW-built executable tries to launch, it either fails or waits. This prevents conflicts in: “Exclusive” in runtime engine usage can mean one

In LabVIEW 6.1, the runtime engine was not inherently multi-session-safe. So “exclusive mode” might be enforced by the application via:

Some organizations or OEMs created “exclusive” redistribution agreements where the LabVIEW 6.1 Runtime Engine could only be bundled with specific certified hardware or software, not freely redistributed. This contrasts with the standard free redistribution allowed by NI. In LabVIEW 6

If you are maintaining a system that still relies on LV 6.1 Exclusive, consider these upgrade paths:
