我还不能发图。就先用文字提示一下。

由于该软件是输入注册码后，会把它保存起来，等到下一次启动的时候再进行验证的，所以，正确的注册码，应该在程序开头进行追踪。

所以如果不使用字符串的话，也是可以的，只要你在开头一直跟进就可以了。

下面提示一下几个关键点：
4F40E2---该关键跳为打开程序时，弹出的那个未注册提示框的跳。程序运行到此便弹出框。
4F3090---注册码最先在这里以明文的方式出现，并作出对比。
4F312A---还可以试用的天数将在这里产生。

总结一下:
1.用户名先转换为HEX,
2.HEX逆序,记做A;
3.固定字符串Pic4ei8espr,记做B;
4.注册码=Lstr(B,1,4)-Lstr(A,1,4)&Lstr(B,5,5)-Lstr(A,5,4)
比如我用户名:inraining
HEX:696E7261696E696E67
逆序后:76E696E6961627E696
注册码:Pic4-76E6ei8es-96E6
