1、把下载的破解补丁放在你的idea的安装目录下的bin的目录下面（如下图所示），本文示例为F:ProgramFilesJetBrainsIntelliJ IDEA 2018.2inJetbrainsCrack-3.1-release-enc.jar 打开IDEA软件，点击免费试用
在这里添加-javaagent:F:Program FilesJetBrainsIntelliJ IDEA 2018.2.1inJetbrainsCrack-3.1-release-enc.jar即可，这时关闭IDEA，并重新打开IDEA 这时在按照如下操作进入注册界面： 
激活代码： Code:{ "licenseId":"1337", "licenseeName":"Downloadly", "assigneeName":"Downloadly", "assigneeEmail":"Downloadly@Downloadly.ir", "licenseRestriction":"Unlimited license till end of the century.", "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":"DPN","paidUpTo":"2099-12-31"},{"code":"RC","paidUpTo":"2099-12-31"},{"code":"PS","paidUpTo":"2099-12-31"},{"code":"DC","paidUpTo":"2099-12-31"},{"code":"RM","paidUpTo":"2099-12-31"},{"code":"CL","paidUpTo":"2099-12-31"},{"code":"PC","paidUpTo":"2099-12-31"},{"code":"DB","paidUpTo":"2099-12-31"},{"code":"GO","paidUpTo":"2099-12-31"},{"code":"RD","paidUpTo":"2099-12-31"}], "hash":"2911276/0", "gracePeriodDays": 7, "autoProlongated": false}
