關於 Visual Studio 2012 RC〔未正確載入套件〕的解決辦法

最近將公司裡其中一台電腦安裝了 Visual Studio 2012 RC，結果在第一次開啟 Visual Studio 2012 RC 的時候卻出現了一連串〔未正確載入套件〕的錯誤，我接著依照先前的文章〔如何在 Visual Studio 2010 發生錯誤時進行問題分析與解決〕所提到的方法進一步追蹤，這才發現原來都是 SQL Server 相關工具沒有正確安裝所導致，這可能跟此電腦之前安裝過太多 Beta 版開發工具的關係，接下來就是解決這次問題的過程與筆記。

首先，我們先來看看發生了哪些錯誤：

以下是在 ActivityLog.xml 檔案中所有的錯誤紀錄：

解決方法很簡單，只要安裝 Microsoft SQL Server 2012 Express Management Studio 即可解決！
註：安裝企業版或開發版的 SQL Server 2012 Management Studio 也可以。
