在網上找了破解IDEA的方法

②然後將這個jar包放入bin目錄下，bin目錄下，你的idea安裝後的bin目錄下 

③然後還是在這個bin目錄下（安裝IDEA的bin目錄），找到這兩個：idea.exe.vmoptions，idea64.exe.vmoptions，（這裡只需要修改一個，如果你是64位的作業系統就修改後者32位則前者）

記事本開啟 
在最後面加入這樣一段（就是這個jar包的路徑，這裡是我的路徑）：-javaagent:D:\IDEA\bin\JetbrainsCrack-2.6.10-release-enc.jar 

④然後重啟idea；Activation code 

然後將這一段複製進來

但是

按照步驟到第四步卻無法重啟IDEA，著實尷尬。後來下載了另一個版本的IDEA還是不行。

最後 索性將IDEA全部解除安裝乾淨，包括下圖也刪除。

然後再 重新下載IDEA進行上述步驟，成功了。

估計是之前有些東西衝突了但是不知道具體是啥。
