Command-Lines Windows Installer provides numerous command-line options and properties to customize the installation and management of an application. You can use multiple command-line options and properties simultaneously to get the result you want. Syntax of Command-Line Options The following is an implementation of the most commonly used command-line options: The executable file for Windows Installer is msiexec.exe. To change the state of a Windows Installer–based application by using a command-line option, the syntax is: msiexec.exe /command line option argument Where argument might be the path and name of a file. If a command-line option requires an argument, the argument must follow directly after the option, separated by at least one space. Command-line options are not case sensitive. Some common command-line options follow: /I installs an application /QB sets the level of user interface to basic /L enables logging To run a normal installation, use the /I switch to msiexec.exe as in the following. Msiexec /I sampleapp.msi If the msi database is not in the current directory for your command prompt, you must specify the full path to the msi file, surrounding the path with quotation marks if it contains any spaces msiexec.exe /i file://server%201234/share/setup.msi to run an installation silently add the switch /qn or /qb to the command line msiexec.exe /i \\server\share\setup.msi /qb msiexec.exe /i \\server\share\setup.msi /qn to uninstall an application, you can use the /x switch msiexec.exe /x file://server/share/setup.msi or msiexec /x {Product Code} to uninstall an application silently msiexec /x file://server/share/setup.msi /qb to advertise a product use the /j switch /jm switch advertises the product of all users of a system and /ju switch advertises the product for only the current user. Applying a transform to an MSI package msiexec /i sample.msi TRANSFORMS=Sample.mst msiexec /i “\\servername\sample.msi” TRANSFORMS=”\\servername\Sample.mst” The following example illustrates enabling verbose logging during an installation without user interface. The log file is called "program.log" and is placed in the TEMP directory. msiexec /qn /l*v “c:\windows\temp\program.log” /i \\server\share\setup.msi
