Silent Switches (working for me in this version):
When doing a silent installation, there are six required arguments. These arguments are case sensitive and are preceded by a double dash (--).
--mode
--unattendedmodeui
--UserName
--CompName
--Serial
--installdir
Options:
--help
Displays a list of valid options
--mode
qt
win32
unattended
Installation Mode
--unattendedmodeui
none
minimal
minimal/WithDialogs
Controls the UI for Unattended mode
--Serial
Serial Number
--UserName
Username
--CompName
Company Name
--installdir
Install Directory
Example: "\\Server\Software\installer\install _Vectorworks2019.exe" --unattendedmodeui none --Serial EDXUSA-XXXXXX-XXXXXX-XXXXXX --UserName <user name goes here> --CompName <company name goes here> --installdir <install directory goes here> --mode unattended
