Uninstall from the Command-Line
● Command line switches and parameters are case-sensitive.
● Be sure to enclose a value that contains one or more special characters, such as a blank space in the command line, in
escaped quotation marks. Command line parameters are case-sensitive.
● Use these installers to uninstall the clients using a scripted installation, batch files, or any other push technology available to
your organization.
● Log files
Windows creates unique child installer uninstallation log files for the logged in user at %temp%, located at C:
\Users\<UserName>\AppData\Local\Temp.
If you decide to add separate a log file when you run the installer, ensure that the log file has a unique name, as child
installer log files do not append. The standard .msi command can be used be create a log file by using /l C:\<any
directory>\<any log file name>.log. Dell does not recommend using "/l*v" (verbose logging) in a command line
uninstallation, as the username/password is recorded in the log file.
● All child installers use the same basic .msi switches and display options, except where noted, for command line
uninstallations. The switches must be specified first. The /v switch is required and takes an argument. Other parameters go
inside an argument that is passed to the /v switch.
Display options can be specified at the end of the argument passed to the /v switch to achieve the expected behavior. Do
not use both /q and /qn in the same command line. Only use ! and - after /qb.
