About the NSIS (Nullsoft) installer

NSIS installers use /S for a silent install. Switches are case-sensitive, and /D= must come last without quotes.

Switch	What it does
`/S`	Silent install (capital S).
`/D=C:\Path`	Install folder. Must be the last switch, no quotes.
`/allusers`	Per-machine install, supported by many but not all NSIS setups.

Install command	`KopiaUI-Setup-0.23.1.exe /S /ALLUSERS`
