About the Inno Setup installer

Inno Setup installers share one set of switches. The uninstaller is usually unins000.exe in the install folder and takes the same silent switches.

SwitchWhat it does
/VERYSILENTNo windows at all.
/SUPPRESSMSGBOXESAnswer message boxes with their default.
/NORESTARTDo not restart after setup.
/SP-Skip the "This will install..." prompt.
/ALLUSERSInstall for all users, if the setup supports both modes.
/DIR="path"Install folder.
/LOG="C:\Temp\install.log"Write a log file.
