Installer Command Line Parameters
| Parameter | Description |
| /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 Setup is very silent, this installation progress window is not displayed. Everything else is normal, so for example, error messages during installation are still displayed, so is the startup prompt (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'. The default response in situations where there's a choice is:
5 message boxes are not suppressible:
|
| /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-parseable; 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'. |
| /DIR="x:\dirname" | Overrides the default directory name displayed on the Select Destination Location wizard page. A fully qualified pathname must be specified. May include an "expand:" prefix which instructs Setup to expand any constants in the name. For example: '/DIR=expand:{pf}\My Program'. |
| /GROUP="folder name" | Overrides the default folder name displayed on the Select Start Menu Folder wizard page. May include an "expand:" prefix, see '/DIR='. If the [Setup] section directive DisableProgramGroupPage was set to yes, this command line parameter is ignored. |
Uninstaller Command Line Parameters
| Parameter | Description |
| /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. |
| /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-parseable; 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. |
