Installation Parameters (Silent, etc.)

/DIR="FULLPATH"

To change the destination suggested by the installer pass.

/TASKS="!desktopicon"

To unchceck the create desktop icon option.

/NORUN

To uncheck the option to run after installation.

/SP

Disables the This will install... Do you wish to continue? prompt at the beginning of Setup. Of course, this will have no effect if the DisableStartupPrompt [Setup] section directive was set to yes.

/SILENT, /VERYSILENT

Instructs Setup to be silent or very silent. When Setup is silent the wizard and the background window are not displayed but the installation progress window is. When a setup is very silent this installation progress window is not displayed. Everything else is normal so for example error messages during installation are displayed and the startup prompt is (if you haven't disabled it with DisableStartupPrompt or the '/SP-' command line option explained above).

/SUPPRESSMSGBOXES

Instructs Setup to suppress message boxes. Only has an effect when combined with '/SILENT' and '/VERYSILENT'.
