算法总结：
1.取公司名zwt进行MD5计算=605B2B8900A9EAB7FBECEB20BD05BDCD
2.将固定字符串QStudio Manager与结果连接得到QStudio Manager605B2B8900A9EAB7FBECEB20BD05BDCD
3.将机器码,上面的结果，“MG5”，“~!@#$%^&*()_+|)(*&^%$#@#^$%&%#$%!@#$”与之连接得到
88770312586996006856QStudio Manager605B2B8900A9EAB7FBECEB20BD05BDCDMG5~!@#$%^&*()_+|)(*&^%$#@#^$%&%#$%!@#$
4.第3步的结果进行MD5计算=83379654E044FCFF85CB2990D7FE3A8A
5.从第12位起取17位和“MG5”连接=MG54FCFF85CB2990D7FE
6.将第5步的结果连接"~!@#$%^&*()_+|)(*&^%$#@#^$%&%#$%!@#$",MD5计算得到DB88D566D49C74F7798082A371E65549
7.将注册码MD5(MG545678901234567890~!@#$%^&*()_+|)(*&^%$#@#^$%&%#$%!@#$)=A2E12E9A296580E1CF3BD6CFE06E684C
两者相等注册成功。
即注册码=MG54FCFF85CB2990D7FE

写注册机算法很简单，有兴趣的可以试试。
