If you are lucky enough to get a software manufacturer to use MSIs for their software your life should be easier when it comes to packaging and installing software, however sometimes you end up with just an .exe installer here’s some switches i’ve found for silent or quiet installers.
setup.exe /s
setup.exe /silent
setup.exe /sms
setup.exe /q
setup.exe /quietSometimes the developers will be nice enough to add help files, so you could run: setup.exe /?
