游戏开始，首先上场的这个程序安装后，运行就弹框了。
国际惯例点注册呗，进来后发现，点复选框勾上同意授权
输入注册码，并数一数注册码多少位呢？ ==》 24
好吧，来吧，直接开搞，来到x32dbg中按下Ctrl+Shift+F , cmp eax, 24
Ctrl+F2 重载程序，果然能断下，但此时断得太早，一切难下定论。
继续走走看看，到处瞧瞧。
我们随便找个查看窗口控件信息的工具吧，得到其类名之类的，然后搜索下：
就得到了兰色圈3，然而下好断点难以断下。
然后我们用x32dbg的字符串增强外员插件过滤搜索看看有啥？ （话说这个插件不能整个复制出来，有点遗憾，我们可以用WinHEX,Ctrl+F10提取啊）
经过简单的提取发现可疑的网址有两个，我们用WinHEX,Ctrl+L 成00保存到目录里,然后原版我们加个.bak扩展名，继续调试原来的文件名的去网址修改版。
黑名单（ 看到这个你想到啥？，显然得改得网络请求呗，比较简单的方法修改hosts)
注册号已被搬~~
无效的授权
注册码格式错误等。。。就不一一说了。
我们本想找找那个无效的小图标的，结果意外发现了下球点和借力点。
下个硬件断点吧~~幸福来敲门了~~
加油~~ 加油~~ 楼主你是好样的~~ 一定能战胜它~~
此时，国际惯例和习惯，Ctrl+A , Ctrl- 到段首~~
查看下，右下角的堆栈区，有没有啥 飞跃点？
貌似当前情况不好也不坏~~
继续前行~~
兰色圈7 有两个下球点
上面的优先回车跟过去看看吧~~
现在感觉情况比刚才好一些了。
上边的此用点共有 7个jmp xxxx 语句
现在感觉好像硬件断点可以禁用或删除了吧？ 建议先禁用，楼主手快给删除了。
此时，我们发现几个JMP中的一个被断下了，堆栈里暴露了新的地址调用点，继续回车跟过去
刚才无用的JMP断也可以删除了

然后我们再来尝试断下小图标
Alt+E,搜索ico，结果发现有多个被断下。
6981FAA0 | 8B11 | mov edx,dword ptr ds:[ecx] ??1QIcon@@QEXXY
但是由于楼主对QT程序还不精通，至少你得编个简单的程序自己爆破找找行情吧，所以此处没分析出关键点来，只看到了注册码取码的部分字符串。
我们再换个思路，从顶层窗口出现的前一时刻开始吧
经过一通周折来到下面的地方
remote Activation And Trial Init 远程激活和试用初始化
上面有几处JCC跳转修改后程序异常了，貌似一下子跳过的内容太多了。
来到上面的地方，原来进入后是个dll文件，修改后没啥效果~~
再去查看下关于，发现了【Demo字样】
[Asm] 纯文本查看 复制代码

也就是说注册版的内容显示为星花儿

012DCDC3 | 68 10753002 | push 7.2307510 | 2307510:"AboutDialog"
通过跨模块搜索，最终锁定了days
00330770 | B8 1E000000 | mov eax,1E 我改成了10000天，当然FFFFFFFF用到死也够用了。
变成注册版，实在绕晕了，不会搞，先到这里吧。
2021.1.31号不死心，再战。。。续传~~
我们搜索【试用模式】操作前先到语言文件夹，把除英文外的QM文件统统移入回收站
我们就会得到下面的执行流
[Asm] 纯文本查看 复制代码 00A46D17 | 68 C006AD01 | push <aTry> | 1AD06C0:"Try"
00A46D1C | 8D45 F0 | lea eax,dword ptr ss:[ebp-10] |
00A46D1F | 68 4C06AD01 | push <aDemowidget> | 1AD064C:"DemoWidget"
00A46D24 | 50 | push eax |
00A46D25 | FFD7 | call edi |

00A46D2A | 8B4B 44 | mov ecx,dword ptr ds:[ebx+44] |

00A46D49 | 6A 00 | push 0 |
00A46D4B | 68 C406AD01 | push <aBuyNow> | 1AD06C4:"Buy now"
然后结合上面找到的 【license mode】
最终我们来到上面的代码处，下面不远处接第一次【试用窗口处】的call处
最终如图修改，我们就过了，那个启动的全部窗口。
试用10000天，28年还不够吗？至于注册还有跟QT程序的走位，以后掌握了窍门再来分析吧，好吧，就到这里吧。
