There is a command line installer for Windows installs which can be used by system administrators, or by other programs calling the Setup program. Here are the details.
Setup Command Line Parameters
The Setup program accepts optional command line parameters. These can be useful to system administrators, and to other programs calling the Setup program.
Also see Uninstaller Command Line Parameters (below).
/HELP, /?
Shows a summary of this information. Ignored if the UseSetupLdr [Setup] section directive was set to no.
/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.
/SUPPRESSMSGBOXES
Instructs Setup to suppress message boxes. Only has an effect when combined with '/SILENT' or '/VERYSILENT'.
The default response in situations where there's a choice is:
Yes in a 'Keep newer file?' situation.
No in a 'File exists, confirm overwrite.' situation.
Abort in Abort/Retry situations.
Cancel in Retry/Cancel situations.
Yes (=continue) in a DiskSpaceWarning/DirExists/DirDoesntExist/NoUninstallWarning/ExitSetupMessage/ConfirmUninstall situation.
Yes (=restart) in a FinishedRestartMessage/UninstalledAndNeedsRestart situation.
The recommended choice in a PrivilegesRequiredOverridesAllowed=dialog situation.
5 message boxes are not suppressible:
The About Setup message box.
The Exit Setup? message box.
The FileNotInDir2 message box displayed when Setup requires a new disk to be inserted and the disk was not found.
Any (error) message box displayed before Setup (or Uninstall) could read the command line parameters.
Any task dialog or message box displayed by [Code] support functions TaskDialogMsgBox and MsgBox.
/ALLUSERS
Instructs Setup to install in administrative install mode. Only has an effect when the [Setup] section directive PrivilegesRequiredOverridesAllowed allows the commandline override.
/CURRENTUSER
Instructs Setup to install in non administrative install mode. Only has an effect when the [Setup] section directive PrivilegesRequiredOverridesAllowed allows the commandline override.
/LOG
Causes Setup to create a log file in the user's TEMP directory detailing file installation and [Run] actions taken during the installation process. This can be a helpful debugging aid. For example, if you suspect a file isn't being replaced when you believe it should be (or vice versa), the log file will tell you if the file was really skipped, and why.
The log file is created with a unique name based on the current date. (It will not overwrite or append to existing files.)
The information contained in the log file is technical in nature and therefore not intended to be understandable by end users. Nor is it designed to be machine-parsable; the format of the file is subject to change without notice.
/LOG="filename"
Same as /LOG, except it allows you to specify a fixed path/filename to use for the log file. If a file with the specified name already exists it will be overwritten. If the file cannot be created, Setup will abort with an error message.
/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' or '/VERYSILENT'.
/NORESTART
Prevents Setup from restarting the system following a successful installation, or after a Preparing to Install failure that requests a restart. Typically used along with /SILENT or /VERYSILENT.
/RESTARTEXITCODE=exit code
Specifies a custom exit code that Setup is to return when the system needs to be restarted following a successful installation. (By default, 0 is returned in this case.) Typically used along with /NORESTART. See also: Setup Exit Codes
/CLOSEAPPLICATIONS
Instructs Setup to close applications using files that need to be updated by Setup if possible.
/NOCLOSEAPPLICATIONS
Prevents Setup from closing applications using files that need to be updated by Setup. If /CLOSEAPPLICATIONS was also used, this command line parameter is ignored.
/FORCECLOSEAPPLICATIONS
Instructs Setup to force close when closing applications.
/NOFORCECLOSEAPPLICATIONS
Prevents Setup from force closing when closing applications. If /FORCECLOSEAPPLICATIONS was also used, this command line parameter is ignored.
/LOGCLOSEAPPLICATIONS
Instructs Setup to create extra logging when closing applications for debugging purposes.
/RESTARTAPPLICATIONS
Instructs Setup to restart applications if possible.
/NORESTARTAPPLICATIONS
Prevents Setup from restarting applications. If /RESTARTAPPLICATIONS was also used, this command line parameter is ignored.
Uninstaller Command Line Parameters
The uninstaller program (unins???.exe) accepts optional command line parameters. These can be useful to system administrators, and to other programs calling the uninstaller program.
Also see Setup Command Line Parameters (above).
/SILENT, /VERYSILENT
When specified, the uninstaller will not ask the user for startup confirmation or display a message stating that uninstall is complete. Shared files that are no longer in use are deleted automatically without prompting. Any critical error messages will still be shown on the screen. When '/VERYSILENT' is specified, the uninstallation progress window is not displayed.
If a restart is necessary and the '/NORESTART' command isn't used (see below) and '/VERYSILENT' is specified, the uninstaller will reboot without asking.
/SUPPRESSMSGBOXES
Instructs the uninstaller to suppress message boxes. Only has an effect when combined with '/SILENT' and '/VERYSILENT'. See '/SUPPRESSMSGBOXES' under Setup Command Line Parameters for more details.
/LOG
Causes Uninstall to create a log file in the user's TEMP directory detailing file uninstallation and [UninstallRun] actions taken during the uninstallation process. This can be a helpful debugging aid.
The log file is created with a unique name based on the current date. (It will not overwrite or append to existing files.)
The information contained in the log file is technical in nature and therefore not intended to be understandable by end users. Nor is it designed to be machine-parsable; the format of the file is subject to change without notice.
/LOG="filename"
Same as /LOG, except it allows you to specify a fixed path/filename to use for the log file. If a file with the specified name already exists it will be overwritten. If the file cannot be created, Uninstall will abort with an error message.
/NORESTART
Instructs the uninstaller not to reboot even if it's necessary.
