ActiveX controls only work with Internet Explorer, as they're part of Microsoft's toolkit. ActiveX控件是Microsoft工具包的一部分，因此只能与Internet Explorer一起使用。 To run an .exe , generally you make a request to a server, which then sends back the response of the output from the program. 要运行.exe ，通常需要向服务器发出请求，然后服务器将程序输出的响应发送回去。 Here's how to do it using PHP and AJAX: 使用PHP和AJAX的方法如下：

$.ajax({
    type: "GET",
    url: 'run-executable.php',
    success: function(data){
        alert(data);
    }
});

On the server, in the file which is called run-executable.php within the directory that your web page is located: 在服务器上，位于您的网页所在目录内的名为run-executable.php中：

<?php exec("/path/to/exe"); ?>

Make sure PHP has permissions to run this on your server. 确保PHP有权在您的服务器上运行它。
