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.

Switch	What it does
`/VERYSILENT`	No windows at all.
`/SUPPRESSMSGBOXES`	Answer message boxes with their default.
`/NORESTART`	Do not restart after setup.
`/SP-`	Skip the "This will install..." prompt.
`/ALLUSERS`	Install for all users, if the setup supports both modes.
`/DIR="path"`	Install folder.
`/LOG="C:\Temp\install.log"`	Write a log file.
