自己亲测：
第一步，下载jar包 ，对于2018.2及以后的版本，JetbrainsCrack-2.10-release-enc.jar这个补丁已经不管用了，请直接去http://idea.lanyus.com下载最新的补丁，按照步骤操作就可以了。
第二部修改：将补丁放在安装包的/bin目录下，并且 分别 对本文件夹(bin)下的idea.exe.vmoptions和idea64.exe.vmoptions这两个文件进行修改，打开文件在末尾添加如下配置指令：
-javaagent:D:/indea/bin/JetbrainsCrack-2.10-release-enc.jar 其中红色部分为自己本机的idea安装目录。
第三步，打开IDEA，进入激活窗口此时需要选择 激活码(Activation code) 的激活方式，并输入刚刚拷贝激活码进行激活
