        public static ActionResult CA_CheckList(Session session)
        {


            if (installer.ListStatus == false) 
            {

                // dispaly
                Record record = new Record();
                record.FormatString = string.Format("Error!");

                   InstallMessage.Error | (InstallMessage)(MessageIcon.Error) |
                   (InstallMessage)MessageButtons.OK,record);

                return  ActionResult.Failure;   

            }
            else
            {

回答1:

This is an old post but I'd like to answer the question in case somebody else finds this. In the custom action definition, CustomAction Id="CA_CheckList" BinaryKey="BIN_CustomAction" ..., 'Return' is set to 'ignore'. It should be set to 'check'.

回答2:

It's all about returning the correct "error code" from the custom action. If you want to terminate the installation, return ActionResult.Failure from your CA.

Side note: displaying UI from inside the custom action is generally a bad idea - this scenario doesn't support silent installation the way it should go.
