原因

1. 注册码有效期太短了，修改过期时间直接到2099年（暂时还没发现问题）
2. 相比于别的方法比较简单
3. 注册码方法似乎只有老版本可用（亲测2.6可用），新版本网上很多注册码方法都失效

具体过程

参考idea破解（这个方法存在问题）

1. idea官网下载2017.3旗舰版
2. 下载一个jar包，链接原文的jar包已经出问题了，用了会在输入注册码那步显示key is valid 所以在这个地址里下新的jar包(破解补丁无需使用注册码，下载地址：http://idea.lanyus.com/jar/JetbrainsCrack-2.6.10-release-enc.jar )一个神奇的连接
3. 后面步骤和第一个连接一致，将jar包拷贝到idea安装目录的bin目录下，我的目录是G:\Program Files\JetBrains\IntelliJ IDEA 2017.3\bin
4. 用记事本或者notepad++打开并修改bin目录下的idea.exe.vmoptions和idea64.exe.vmoptions两个文件

   

   在最后一行均添加-javaagent:G:\Program Files\JetBrains\IntelliJ IDEA 2017.3\bin\JetbrainsCrack-2.6.10-release-enc.jar，注意这里的目录和你的idea目录一致
5. 启动idea，在注册界面选择active code，输入下面的注册码
