Using MSI Script
Installer installation you create, but each mode is run only under certain circumstances.
Installation modes are not used with merge modules.
For information on dialog box groupings, see About Dialogs on page 449.
Normal Installation
Select this installation mode to edit the sequences that are run during a normal
installation. This is the most common type of installation.
If the application is not already installed when an end user double-clicks the installation
.MSI, the standard installation wizard appears (Install Dialogs), which installs the
product. If the application is already installed when an end user double-clicks the
installation .MSI or if the end user selects it from the Add/Remove control page, the
installation runs in maintenance mode (Maintenance Dialogs), which provides options to
modify, repair, or uninstall an application.
Administrative Installation
Select this installation mode to edit the sequences that are run during an administrative
installation.
An administrative installation copies a source image of the application to a network; the
source image resembles the directory structure of the installed application. End users
who have access to the administrative installation can then install the application from
the network location.
To run an administrative installation, use the command-line option /a. (Example:
msiexec /a "C:\path\Sample.msi".) An administrative installation uses the Admin
Dialogs.

Advertisement Installation
Select this installation mode to edit the sequences that are run during an advertisement
installation.
An advertisement installation places entry points, such as shortcuts, on the destination
computer without actually installing the application. When an installation is opened in
advertising mode, only the Execute sequences are run because it does not have a User
Interface sequence, and therefore no dialog boxes appear. See Advertisement in the
Windows Installer SDK Help.
To run an advertisement installation, use the command-line option /j. Example: msiexec
/j "C:\path\Sample.msi".
All Custom Actions
Select All Custom Actions from the Installation Mode drop-down list to view the All
Custom Actions list. The All Custom Actions list does not represent an installation mode,
but instead is a repository of all custom actions stored in the CustomAction table of this
installation.
Use All Custom Actions to do the following:
