Setup Command-line Options and Property
When you run Setup you can use command-line options to change some of the parameters that Setup uses to install the application, such as display settings and default values for Setup properties.
Setup and Windows Installer use properties to control the applications installation process. The default values for Setup properties are defined in the Windows Installer package (MSI file). You can specify new property values on the command line or in the Setup settings file (Setup.ini).
Note In most cases, command-line options override duplicate customizations in the Setup settings file (Setup.ini) or in a transform (MST file). Command-line options and properties are not supported by all MSI files.

/a [msifile]
Create an administrative installation point for the specified package (MSI file). The package must be in the same folder as Setup.exe, and both must be at the root of the administrative installation point.
Examples:

/a "subfolder1\My.msi"
/f[options][msifile]
Force repair of an application associated with the specified package (MSI file). The package must be in the same folder as Setup.exe, and both must be at the root of the administrative installation point. Alternatively, you can specify the product code for the package the product code can be copied from the [Product] section of the Setup settings file.
Note You must specify the same package that was used to install the application originally.
