/SILENT, /VERYSILENT

The wizard and background window are not displayed but the installation progress window is. When a setup is very silent, the progress window is not displayed. Error messages during installation are displayed.  If a restart is necessary and the /NORESTART command isn't used and Setup is silent, it will display a Reboot now? message box. If it's very silent, it will reboot without asking.

/SUPPRESSMSGBOXES

Suppresses messageboxes. Only has an effect when combined with /SILENT and /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.

/LOG

Creates 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-parseable; the format of the file is subject to change without notice.

/LOG="filename"

Same as /LOG, except it allows specifying 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 cancelling the installation process by disabling the Cancel button and ignoring clicks on the close button. Useful along with /SILENT or /VERYSILENT.

/NORESTART

Does not reboot even if necessary.

/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.

/NOICONS

Initially checks the Don't create any icons checkbox on the Select Start Menu Folder wizard page.

/TYPE=type

Specifies a setup type for the Select Components wizard page (full, compact, or minimal).

/COMPONENTS="comma separated list of component names"

Specifies components for the Select Components wizard page (required, application, samples, addins, and/or tools), selecting a custom installation type.  Only the specified components will be selected; the rest will be unchecked.  If a component name is prefixed with a "!" character, the component will be unchecked.

/TASKS="comma separated list of task names"

Specifies a list of tasks from the Select Additional Tasks wizard page (desktopicon, quicklaunchicon, assoc, and/or explorer) that should be selected.  Only the specified tasks will be checked; the rest will be unchecked. If a task name is prefixed with a "!" character, the task will be unchecked.
