@NEGIA that is not true:
The command line parameters for silently installing or uninstalling an application can vary widely depending upon the application. I’ve only seen /SILENT or /VERYSILENT on particular Microsoft products, but of course these could be in others as well.
MSI-based installers can usually use “/qn” for “Quiet/No Interface”, along with “/i” for install or “/x” for uninstall. A very small number of MSI packages are authored in a way where silent install/uninstall doesn’t work properly.
InstallShield-based applications usually need to use “/s” for silent, along with “/v/qn” in order to pass the “/qn” parameter along to an embedded MSI package that InstalLShield usually uses.
InstallAnywhere packages use different parameters (which I don’t recall at the moment).
Symantec packages their antivirus with different parameters.
For MSI packages I usually start with “msiexec /i package.msi /qn ALLUSERS=1 REBOOT=ReallySuppress” and see how that works.
In general if you don’t know, the “unattend” search term helps in google. For instance “chrome install unattend”
