大家来帮我改一下代码，为什么生成exe后达不到预期效果呢？

文件下载转移没问题，注册表也没问题，就是无法播放那个wav文件，问什么？

谢谢了

mciExecute "play C:\WINDOWS\system32\demo.wav"

你确定可以这么写？

奇怪阿 我这里正常
你看看是不是wav文件坏掉了
你运行的时候执行到mciExecute "play C:\WINDOWS\system32\demo.wav"的时候有错误提示么，这个函数比较特殊，如果出错的话会有对话框弹出，否则的话说明运行正常。
你试试单独执行这一句看看（这个函数的参数里的路径一定要用8.3格式的）。
实在不行的话试试sndPlaySound这个函数
