１、從 IntelliJ IDEA的官網：https://www.jetbrains.com/選擇旗艦版下載。
選擇Ultimate版本：
２、下載完成之後，去http://idea.lanyus.com/jar/JetbrainsCrack-3.1-release-enc.jar 下載一個JetbrainsCrack-3.1-release-enc.jar破解補丁。完成後放在安裝idea下面的bin的目錄下面。
３、在安裝的idea下面的bin目錄下面有2個文件 ： 一個是idea64.exe.vmoptions，另外一個是idea.exe.vmoptions．
４、用記事本打開上述的兩個vmoptions文件，在其末尾添加一行代碼：-javaagent:破解補丁路徑，如下圖所示。
５、重啓一下軟件，因爲我們下載的破解補丁是無需註冊碼的，所以至此破解結束。（如若出現有active code選擇界面的時候 寫入下面註冊代碼即可（（到2099年到期）：
