Inno Setup

Inno setup is an installer framework made by jrsoftware.org. It is a super cool and FREE tool for making executable setup programs.

Inno Setup Recommendations

I recommend that you use the /VERYSILENT and /SUPPRESSMSGBOXES as fixed parameters for the uninstall of the wrapped setup. This ensures that the uninstall of the wrapped product only shows  the MSI dialogs.

Install Command Line Switches

/SP-

Disables the This will install... Do you wish to continue? prompt at the beginning of Setup.

/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 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' 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.

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 message box displayed by code.

/LOG

Causes Setup to create a log file in the user's TEMP directory detailing file installation and 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.)

/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.

/NOCLOSEAPPLICATIONS

Prevents Setup from closing applications using files that need to be updated by Setup.

/NORESTARTAPPLICATIONS

Prevents Setup from restarting applications. If Setup didn't close these applications (for example because /NOCLOSEAPPLICATIONS was used), this command line parameter is ignored.

/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.

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. 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='.

/NOICONS

Instructs Setup to initially check the Don't create a Start Menu folder check box on the Select Start Menu Folder wizard page.

/TYPE=type name

Overrides the default setup type.

If the specified type exists and isn't a custom type, then any /COMPONENTS parameter will be ignored.

/COMPONENTS="comma separated list of component names"

Overrides the default component settings. Using this command line parameter causes Setup to automatically select a custom type. If no custom type is defined, this parameter is ignored.

Only the specified components will be selected; the rest will be deselected.

If a component name is prefixed with a "*" character, any child components will be selected as well . If a component name is prefixed with a "!" character, the component will be deselected.

/PASSWORD=password

Specifies the password to use.

When an invalid password is specified, this command line parameter is also ignored.

Uninstall Command Line Switches

/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. 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.)

/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.
