LabVIEW 6.1 executables require a runtime engine by LV5.0 did not?

[Tim.S]

I've built executable applications with LV 5.0 and ran them on computers without the LV runtime engine (or any NI software).
Now I've upgraded to LV6.1 and it seems the runtime engine needs to be included with all applications.

Do all applications built with LV6.1 need the runtime engine or only those which use DAQ, GPIB, etc?

Was the runtime engine included as the default in LV5.0 so I never had to choose it before?
(I did notice that the file size for LV5.0 executables are much larger.)

I guess I'm looking for clarification between the two LV versions.

The difference is that in the older versions of LabVIEW, the run-time engine was part of the .exe and that's why the files were much larger. With version 6 and above, the run-time engine is separate and every LabVIEW executable needs it. The advantage of a separate run-time is that if you have multiple .exe files to install, the engine only needs to be installed once.
