開始安裝後有一步驟要輸入序號，這時請到信箱找Embarcadero-licensing寄來的信
Serial Number(s)就是你的序號了

再來選擇要安裝的功能，一般初學不需要那麼多功能，可以不要安裝

如果剛才有勾選Android Development Platform，下一步會跳出Android SDK/NDK Installation
這是在C++Builder XE6新增的功能，讓你可以用C++利用Firemonkey FMX開發Android應用程式！
如果你是進階開發者且電腦已經安裝過SDK/NDK則可以不勾選，在安裝完後再設定位置
否則在此建議都打勾讓安裝程式幫你下載並設定
不過往後的教學不包含教你用C++Builder開發Android應用程式，因此有興趣的人可以自行研究

接下來就一直按Next直到開始安裝
安裝過程由於會透過網路下載安裝檔案，因此請保持網路連線

安裝完成後，從開始功能表找到Embarcadero RAD Studio XE6執行C++Builder XE6
會出現註冊畫面，上面的序號就是你的安裝時輸入的試用序號，點擊Rgister就能註冊你的序號了

成功囉！
