The Update Installation program accepts optional command line parameters. These can be useful to system administrators, and to other programs calling the Setup program.
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.
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.
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.
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.
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'.
Instructs Setup not to reboot even if it's necessary.
Specifies the custom exit code that Setup is to return when a restart is needed. Useful along with '/NORESTART'. Also see Setup Exit Codes.
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.
Specifies the password to use. If the [Setup] section directive Password was not set, this command line parameter is ignored.
When an invalid password is specified, this command line parameter is also ignored.
|·||Exit codes :|
|0||Setup was successfully run to completion.|
|1||Setup failed to initialize.|
|2||The user clicked Cancel in the wizard before the actual installation started, or chose "No" on the opening "This will install..." message box.|
|3||A fatal error occurred while preparing to move to the next installation phase (for example, from displaying the pre-installation wizard pages to the actual installation process). This should never happen except under the most unusual of circumstances, such as running out of memory or Windows resources.|
|4||A fatal error occurred during the actual installation process.|
Note: Errors that cause an Abort-Retry-Ignore box to be displayed are not fatal errors. If the user chooses Abort at such a message box, exit code 5 will be returned.
|5||The user clicked Cancel during the actual installation process, or chose Abort at an Abort-Retry-Ignore box.|
|6||The Setup process was forcefully terminated by the debugger (Run | Terminate was used in the IDE).|
Before returning an exit code of 1, 3, or 4, an error message explaining the problem will normally be displayed.
Future versions of InnoSetup may return additional exit codes, so applications checking the exit code should be programmed to handle unexpected exit codes gracefully. Any non-zero exit code indicates that Setup was not run to completion.
