The LabVIEW 6.0.2 update has the following options. However, I don't know if the LV Run-Time engine has them as well.
The updater may be run with the following options:
/l -- to generate a log file. To use this option from the start menu type "
\setup.exe /l c:\lv602updatelog.log"
/q -- for silent installations (no user prompts)
/m- suppresses mass compilation
