MSI Silent Uninstall

We are trying to run a silent uninstall on a MSI that was originally created in Install Shield, not sure what version. When using the standard command line arguments it suppresses all prompts with the exception of the Maintenance Window. Even using different combinations of the q switch (q, qn, qb, qb! , etc....) as well quite switch. Since we doing this as an automated uninstall there will be no user at the workstation. Any help would be greatly appreciated. Thanks.

It seems to me that you may be missing /x in your command line. /x is required for uninstallation of MSI. Since it is not passed, your package is trying to run the installation again and is getting into maintenance window as it is already installed on the machine.
