32bit Convert It 9.52.01破解手记

32bit Convert It 9.52.01破解手记--找到注册码

作者：newlaos[CCG][DFCG]

软件名称：32bit Convert It 9.52.01(理科工具)

整理日期：2003.4.4

最新版本：9.52.01

文件大小：343KB

软件授权：共享软件

使用平台：Win9x/Me/NT/2000/XP

发布公司：http://www.electrasoft.com/

软件简介：32bit Convert It 让你不用再翻遍单位换算表就能直接在软件上面执行单位换算的工作，有相当多种类的单位换算功能。

加密方式：注册码

功能限制：未注册信息提示

PJ工具：TRW20001.23注册版，W32Dasm8.93黄金版，FI2.5

PJ日期：2003-04-09

作者newlaos申明：只是学习，请不用于商业用途或是将本文方法制作的注册机任意传播，造成后果，本人一概不负。

1、先用FI2.5看一下主文件“32bc.exe”，没加壳。程序是用VC++6.0编的

2、用W32Dasm8.93黄金版对32bc.exe进行静态反汇编，再用串式数据参考，找到"Thank you for registering "

双击来到下面代码段。

3、再用TRW20001.23注册版进行动态跟踪，下断BPX 0040B3A8(通常在注册成功与否的前面一些下断，这样，才能找到关键部分)，

先输入姓名：newlaos

假码: 78787878

4、用KEYMAKE 1.73制作内存注册机

一、选择F8 → 另类注册机！

程序名称：32bc.exe

添加数据：

中断地址：0040B538

中断次数：1

第一字节：83

指令长度：3

保存下列信息为注册码 → 内存方式 → 寄存器 → EDI

二、选择内存方式：内存地址 → 0044B54C → 点生成，就有你乐的了

5、我的注册信息保存在32bitcvt.ini文件里:

我的注册信息：

NAME:newlaos[CCG]

CODE:30353935353E

EMAIL:newlaos@km169.net
