一、下载并安装IDEA

官网：https://www.jetbrains.com/idea/

二、修改文件

1、将下载的文件放到安装IDEA路径的bin目录下（如图），需要插件的可以联系我

IDEA的bin目录
2、在IDEA路径的bin目录下找到idea.exe.vmoptions和idea64.exe.vmoptions，用notepad++（或记事本）打开，在两个文件最后分别加上以下内容（注意：要修改JetbrainsCrack的路径。）

-javaagent:C:\Program Files\JetBrains\IntelliJ IDEA 2018.3.2\bin\JetbrainsIdesCrack-4.2-release.jar

三、修改Activation Code

1、重启Intellij IDEA，在Activation Code输入以下内容

ThisCrackLicenseId-{
"licenseId":"ThisCrackLicenseId",
"licenseeName":"你想要的用户名",
"assigneeName":"",
"assigneeEmail":"idea@163.com",
"licenseRestriction":"For This Crack, Only Test! Please support genuine!!!",
"checkConcurrentUse":false,
"products":[
{"code":"II","paidUpTo":"2099-12-31"},
{"code":"DM","paidUpTo":"2099-12-31"},
{"code":"AC","paidUpTo":"2099-12-31"},
{"code":"RS0","paidUpTo":"2099-12-31"},
{"code":"WS","paidUpTo":"2099-12-31"},

{"code":"PC","paidUpTo":"2099-12-31"}
],
"hash":"2911276/0",
"gracePeriodDays":7,
"autoProlongated":false}
