If
you need to start an MSI installation (Windows Installer
installation) with command line parameters, you must run the MSIEXEC.exe
program that is distributed with Windows Installer. Since
Windows XP, all versions of Windows has this program included,
so it is safe to call this program.
The
MSIEXEC
script command in Visual Installer calls this program
automatically, and all command line parameters that you specify
via this command's second parameter (the %Param
parameter) are passed to the MSIEXEC.exe program. A
complete list of available command line parameters (command line
switches) is available
on this page on Microsoft's website.
The
MSIEXEC
script command automatically includes the /i parameter
(normal installation) in the command line, unless you specifies
it by yourself, or if you specifies the /a
(administrative installation) or /x (uninstall)
parameter. In these cases, /i will not be added to the command line.
When you run the MSIEXEC.exe program, you must also
specify a full path to the MSI file (a full path to a file with
an ".msi" filename extension). When you use the
MSIEXEC
script command, you specify this via the first parameter of the
command (via the %Filename parameter).
