========================================
注册流程大致为
用户名,版本号,两个条件来算码
版本号有三个,分别是
Home Edition
Office Edition
Commercial Edition
软件特征码:BDDEEE28-4FE9-4E2E-B24A-E92F2881512C
1.转大写(MD5(转大写(用户名 & MAGIC EXCEL RECOVERY & 版本号 & 软件特征码)))
2.取MD5值的ASCII转十进制,然后取十进制的个位
3.取四个加入一个“-”,共取四组
三个版本的注册码都不一样
比如我的crackvip
则有三组注册码都可以用
分别是
Home Edition:7125-0277-6151-8014
Office Edition:9955-9650-9549-9857
Commercial Edition:1060-6466-7629-8054
注册信息保存在注册表
HKEY_CURRENT_USER\Software\East Imperial Soft\Magic Excel Recovery 1.0\Settings
删除了之后可以重新注册
