脱完壳了想写注册机没有头绪也找到机器码和注册码位置

里面有两份一份脱完了一分没脱完想请教一下如何编写注册机

不知道能不能用

运行不起来中，能发个完整的安装包吗？

注册过程：机器码经过GetCode()计算后变成激活码的一部分，最终的激活码 跟FindClass.RegistIt()进去 分析吧。

文件包不完整，另外需要管理员才能注册成功，因为Registry.LocalMachine.OpenSubKey
注册码以[分隔为8段(0-7)：GetCode(申请码)[有效期[随意日期[随意字符[随意字符[随意字符[随意字符[随意字符

byh3025

把注册类型改为true，

可以激活但是里面功能并不能使用
