**************************************************************
一、运行程序,进行注册,输入错误的注册信息进行检测,有提示信息"wrong serial number"
**************************************************************
二、用PEiD对这个软件查壳,无壳,为 Microsoft Visual C++ 6.0编写
**************************************************************
三、运行OD,打开Recorder,右键—超级字串参考—查找ASCII.
找到“wrong serial number”了,双击,来到
