What is the command line to silently install an MSI file?
Quiet display option.
The installer runs an installation without displaying a user interface.
msiexec /package Application.msi /quiet msiexec /uninstall Application.msi /quiet msiexec /update msipatch.msp /quiet msiexec /uninstall msipatch.msp /package Application.msi / quiet
Note The equivalent Windows Installer Command-Line Option is
run this command to find more information about the installation options.
UPDATE June 2018: Although the tool shown below is no longer available for download, I found it via Wayback machine. I assume it is OK and legal to link to it, seeing as the tool was freeware. Updated links below.
UPDATE: This tool from Wise is regrettably not downloadable anymore. I am not sure if it is OK to distribute it either. It seemed to be a free tool distributed as part of their main Wise Package Studio suite, but I don't think it is open source. I wish they would release it as an open source tool.
The Wise packaging products have been discontinued due to a number of legal issues.
UPDATE June 2018: http://www2.wise.com/filelib/WICLB.exe - broken link resurrected from Wayback machine. Seeing as the tool was freeware I assume that is legal. Please run the download by virustotal.com for safety.
I am very experienced with msiexec.exe, but the command lines are so long that it is easy to make mistakes. I prefer to generate the complex ones and eliminate that error source.
N.B: hope posting download links to tools is ok! I am not affiliated with Altiris in any way. It's a free tool, it's easy to use and it works. Here is a screenshot:
See the docs for "Unattended": http://unattended.sourceforge.net/installers.php
In short, while there are ways to cause them to fail, these flags should work:
msiexec /qb /i blah.msi REBOOT=ReallySuppress
There's also these:
/q , /qn No UI. /qb Basic UI. /qb! Basic UI with no cancel button. /qr Reduced UI. A modal dialog box is displayed at the end of the install. /qf Full UI. A modal dialog box is displayed at the end of the install. /qn+ No UI. However, a modal dialog box is displayed at the end of the installation. /qb+ Basic UI. A modal dialog box is displayed at the end of the installation. If you cancel the installation, a modal dialog box is not displayed. /qb- Basic UI with no modal dialog boxes.
