Do you want the complete or success property? You are confusing the xhr object's .done() with ajax setup property complete: or success: I think.

Done's second parameter is a status, not the data.

Try this instead

 $(document).ready(function() {
            $('#fileupload').fileupload({
                dataType: 'json',
                url: '/Admin/Image/UploadFiles',
                autoUpload: true,
                success: function (data, status, xhr) {
                    alert(data.message); 
                    if (data.message== 'success') {
                        alert(data.message);
                        window.location = "www.google.com";
                    }
                }
            })
