IIRC, you can't remove values in Custom Action, only add them.

Subject: [wix-users] Update ActionText table in MSI DB using Immediate CA before LaunchConditions

I need to clear out the Description column values for some of the actions from the ActionText table in the msi db. For this, I created an Immediate CA to be triggered before Launch Conditions. I followed the links below to do the update with the below code, but I am not able to get it working. I keep getting the error, "Function failed during execution.".



using (Database db = session.Database)
                    if (db.Tables.Contains("ActionText"))
                        string actionName = "Name of the Builtin Action";
                            //db.Execute("UPDATE ActionText SET Description = '' WHERE Action = '" + actionName+ "'"); // not working

                            string query = "SELECT * FROM ActionText WHERE Action = '" + actionName + "'";
                            View view = db.OpenView(query);
                            using (Record record = view.Fetch())
                                record.SetString("Description", " ");
                                view.Modify(ViewModifyMode.Assign, record); //error here
                                //view.Update(record); // this is also not working

Can anyone please help?
