Additional parameters for silent installs with Inno Setup

[Scott G. <sco...@ho...>]

The parameters listed below should be helpful to anyone trying to do a
silent install with an Inno Setup program.  The information on the
unattended web site is incomplete and only mentions the /silent
parameter, which in my experience is insufficient (use "setup.exe /sp-
/verysilent" instead).  Perhaps the web page (link below) should be
updated to include this information.

This information is included with the Inno Setup program (in the
ISetup.hlp file) available for download here:

The Setup program accepts optional command line parameters. These can be
useful to system administrators, and to other programs calling the Setup
program. 
 
/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) 
 
If a restart is necessary and the '/NORESTART' command isn't used (see
below) and Setup is silent, it will display a Reboot now? message box.
If it's very silent it will reboot without asking. 
 
/NOCANCEL 
Prevents the user from cancelling during the installation process, by
disabling the Cancel button and ignoring clicks on the close button.
Useful along with /SILENT. 
 
/NORESTART 
Instructs Setup not to reboot even if it's necessary. 
 
/LOADINF="filename" 
Instructs Setup to load the settings from the specified file after
having checked the command line. This file can be prepared using the
'/SAVEINF=' command as explained below. 
 
Don't forget to use quotes if the filename contains spaces. 
 
/SAVEINF="filename" 
Instructs Setup to save installation settings to the specified file. 
Don't forget to use quotes if the filename contains spaces. 
 
/LANG=language 
Specifies the language to use. language specifies the internal name of
the language as specified in a [Languages] section entry. 
When a valid /LANG parameter is used, the Select Language dialog will be
suppressed. 
 
 
/DIR="x:\dirname" 
Overrides the default directory name displayed on the Select Destination
Location wizard page. A fully qualified pathname must be specified. 
                            
/GROUP="folder name" 
Overrides the default folder name displayed on the Select Start Menu
Folder wizard page. If the [Setup] section directive
DisableProgramGroupPage was set to yes, this command line parameter is
ignored. 
 
/NOICONS 
Instructs Setup to initially check the Don't create any icons check box
on the Select Start Menu Folder wizard page. 
 
/COMPONENTS="comma separated list of component names" 
Overrides the default components settings. Using this command line
parameter causes Setup to automatically select a custom type.
