I've been informed by NI support that current versions of LabVIEW can only be installed silently by installing Package Manager first and then using batch scripts for installation. Previous versions of labview supported silent installation using typical msiexec flags. The current tool, INSTALL.EXE only supports a passive switch which requires an interactive gui for it to successfully run an installer with application options other that the Package Manager. This is far from an ideal situation for mass deployment to computer labs and it ends up causing a waste of time and effort. Please add silent installation options to install.exe and add the ability for INSTALL.EXE to show installation parameters when it is passed some sort of common help parameter (such as --help, -h, -? ).
