破解的详细过程：

1.从下面地址下载一个jar包，名称是  JetbrainsCrack-2.10-release-enc.jar

下载地址是http://idea.lanyus.com/，进去之后点击这个网址 。

2.将你下载好的JetbrainsCrack-2.10-release-enc.jar拷贝到你的Idea安装目录的bin目录下。 

3.接下来在bin目录下找到两个vmoptions文件，idea.exe.vmoptions和idea64.exe.vmoptions如下图所示。

4。将这两个文件用记事本或者写字板打开，在两个文件最后一行添加：-javaagent:E:\IntelliJ IDEA 2017.1\bin\JetbrainsCrack-2.10-release-enc.jar。

注意：-javaagent:后加的是自己刚才所添加的JetbrainsCrack-2.10-release-enc.jar的具体路径。

5.接下来重新启动idea软件，复制以下内容到Acrivation code中的空白处。
