更新Norton病毒碼出現問題！

請問一下，我現在用的是Norton 7.0 企業版，產品版本是 1.3.5.11，之前下載最新病毒碼（20030711-018-i32-1.exe），在win2000的系統下安裝，結果安裝出現錯誤，中間中斷好幾次，並且最後出現以下訊息：
A Symantec product containing virus protection was found and was updated. This product uses the latest engine and virus definition system available.However,kf you have other older Symantec products,in addition to those detected,you must run Intelligent Updater version 2 to update their virus protection.
然我再開啟Norton，發現並沒有更新，怎麼會這樣呢？
