Solution
When an installer is created for a LabVIEW executable, you have the option to include the LabVIEW Run-Time Engine required to run the compiled program.
While the installer does install the LabVIEW Run-Time Engine, it does not create a separate entry within Add/Remove Programs in the Windows' Control Panel. If you need to uninstall the Run-Time Engine, you can do so by uninstalling the entire application that was built, as the application name should still be listed in the Add/Remove Programs list.
Note: The LabVIEW Run-Time Engine keeps track of all programs that installed it, so if you ran several installers, you will have to uninstall all of them in order to completely remove the LabVIEW Run-Time Engine from the computer.
