class MsiException(Exception):
    """Raised when there are issues with the msi actions."""
 
 
def uninstall_product(uid):
    """Will remove the old beta from the users machine."""
    # we use the msi lib to be able to uninstall apps
    property_name = u'LocalPackage'
    uninstall_path = get_property_for_product(uid, property_name)
    if uninstall_path is not None:
        # lets remove the package.
        command_line = u'REMOVE=ALL'
        result = windll.msi.MsiInstallProductW(uninstall_path, command_line)
        if result != ERROR_SUCCESS:
            raise MsiException('Could not remove product %s' % uid)

The missing functions can be found in the last post about the topic.
