====================写在前面====================
上次一个截图软件的破解思路，我已经放出来了。本来以为那是比较年轻的软件里面很好破解的了，没想到来了个更软的柿子。它的名字就叫做EasyRecovery，最近有了中文代理官方，所以它的中文名就叫做易恢复了，我冒险说出来吧。
这个软件我偷懒修改破解者信息了，所以加不加壳其实又是没用的了，顺便也就放出来了。额......

====================破解过程====================
<方法一>查找字符串......
PEiD查壳，显示：UPolyX v0.5 [Overlay] *
估计是误报，再看一下：
平均信息量：5.94 (未加密)
EP 检查：未加密
快速检查：未加密
那就确认是误报了，软件作者可能对头部做了点手脚，或者说加的壳太菜了，跟没加一样。我们不用去管它。
查找字符串，然后有5059个。看来软件代码的可读性是不错的。

我为了防止暗桩所以把所有功能限制也去掉了。不知不去掉会不会还有功能限制啊，节省时间不测试了吧。

<方法二>调用注册子程序时下手

这个程序有一个特点，就是说主程序检测到未注册的时候，子程序就会调用.\licman\licman.exe，呵呵。我们从这个入手(我本来还以为调用子程序主程序会关掉，后来试了一下，发现它不会关掉主程序，所以好弄多了。)

运行起来！！调用了子程序以后，F12暂停主程序，看堆栈调用。

上面所示的地方，看到了吧，这个je很可疑，我们可以在这里下断，重载程序，看看情况。
由于它在调用Call的下面，所以要点击那个子程序的"作为演示运行"按钮，然后程序就被成功断下了。
断下以后，会发现跳转没有实现，那我们改一下Z标志位先试一下。
界面上面没有Demo字样了，想想应该也没有功能限制了，拿同学送我的U盘试试。
(此U盘他是删光东西以后给我的，但是......应该没有安全删除，所以......顿时发现我好邪恶.)
扫描了二十几秒，拿一个30几M的视频一试，啊哈，成功了。
于是重载程序，想当然就把这里改为jmp......等等！那么licman这个注册子程序还是会被唤出的！我们得从根源上解决问题！(完美才舒服。)
我们在段首，也就是004B8680:push ebp这里下断。
重载程序，会发现，licman还是出来了。(有点想揍这个man)
于是我们可以大胆地猜想，我们进的Call太深了，我们退出一层Call.

从段首到段尾：(这次是没办法，必须得都贴上了，不会被说是灌水吧？)

看到，有四个跳转可以跳过这个Call。我一般习惯改最前面的。试试。
因为不能同时运行两个EasyRecovery，所以我们保存文件以后，就把OD运行处下断点，然后重载程序，执行一下我们Cracked的程序。
果然，改了第一个跳转的就不会再呼出licman了，而且很完美，没有暗桩哦。;-)

后面三个跳转我也试了一下，都不行。具体原因也来看看吧，在这个段的段首下断。
跟踪后发现：004B84AB |. E8 7092F4FF call <jmp.&kernel32.CreateProcessW> ; \CreateProcessW
这个调用了子程序！呵呵，看来还找得不完全啊。
那么我们前面：004B8470 |. /0F85 AD000000 jnz EREnt.004B8523
这个跳转改成jmp试试。(后面那三个跳转随便改一个哦。)
会发现，这次OK了。试试有没有限制。木有暗桩。哈哈。

到此，两个方法都讲完了，我也累了。
总结一下，看来这个程序就是调用licman，如果反馈给它是使用Demo的，那么再进行增加Demo的限制。
如果什么也不反馈，或者licman根本就没有运行过，那么就是作为完整版运行啦！！
所以，我们还可以......

<方法三>从licman.exe下手(最便捷方法)

由于这个程序调用licman.exe，如果没有它，主程序也无法运行。但是我们可以直接对licman.exe，把这个man给disable了！呵呵。

载入后得：

0059F730 >/$  C605 30806200>mov byte ptr ds:[628030],0
0059F737  |.  E8 B4FFFFFF   call licman.0059F6F0
0059F73C  |.  B8 10F46200   mov eax,licman.0062F410
0059F741  |.  E8 1A28E7FF   call licman.00411F60
0059F746  \.  C3            retn

我们直接把retn以外的所有代码nop掉即可。
然后打开主程序一看，就没有licman的阻挡了，直接就是完整版！

以上是所有方法，菜鸟希望大家的支持哈！

====================写在后面====================
   呵呵，这个程序破解也很简单吧？为什么我不贴图呢？因为我感觉贴图能贴什么？就贴个软件界面？那还不如自己下载好好观看呢。代码基本也都贴好了，应该不需要图了吧......
   还有有人提议让我多花点时间学习啊呵呵。这都是我抽时间搞出来的，零碎时间......不过说的也是啊，我以后发主题帖隔的时间可能会更长一些。
   希望大家支持一下。这个程序已经比上一个要好破解得多了，尤其是最简单的方法，那个方法叫做......程序员设计程序时考虑不周到而产生的。呵呵，就连我发现时也大吃一惊呢！
