【破解过程】一、脱壳 工具简单搞定
二、通过bp MessageBoxA这个断点 很快找到这里：

【破解总结】
算法超级简单
逐位取用户名ASCII码 再首尾串起来 结果设为A
与固定值 CMW201118 串起来 格式为 CMW201118-A 即为真码
E语言注册机源码：
.版本 2

.局部变量 name, 文本型
.局部变量 len, 整数型
.局部变量 sn, 文本型
.局部变量 i, 整数型
.局部变量 C, 文本型
.局部变量 sum, 文本型

name ＝ 编辑框1.内容
len ＝ 取文本长度 (name)
.计次循环首 (len, i)
C ＝ 取十六进制文本 (取代码 (name, i))
sum ＝ sum ＋ C
.计次循环尾 ()
sn ＝ “CMW201118” ＋ “-” ＋ sum
编辑框2.内容 ＝ sn
