You can also silently uninstall ClearCase from target computers, providing you have version 2003.06.00 installed.
To do this, execute this command:
msiexec.exe /X path/clearcase.msi /qn
path is the path to a file (clearcase.msi), found in your networkwide release area in the Setup directory, used by ClearCase during installation. /X indicates that an uninstall operation is executed. /qn indicates that no user interface is displayed during the uninstall operation.
Note: You must specify the pathname for clearcase.msi when executing this command.
To silently uninstall a previous version of ClearCase, see the documentation associated with that version.
For more information about msiexec.exe and associated command-line options, see the Microsoft Windows Installer Platform Software Developer’s Kit documentation at http://www.microsoft.com/windows/reskits/webresources/default.asp.
