最近因為某些軟體更新了，導致 WebMatrix Crash，更新到 WebMatrix Beta 2 後，發現到原本的專案有些內容會出錯，懶得一個個改，只好再依照下面的步驟安裝回 WebMatrix 1，沒想到問題還是沒解決 @_@

1. Uninstall Web Platform Installer
2. Uninstall WebMatrix Beta 2
3. Uninstall IIS 7.5 Express
4. (If you installed PHP for WebMatrix) Delete the remaining PHP folder under C:\Program Files (x86)\IIS Express
5. Install Web Platform Installer 3.0 (http://www.microsoft.com/web/downloads/platform.aspx)
6. Install WebMatrix 1 from the Web Platform Installer 3.0
6. (If desired) Install PHP for WebMatrix from the Web Platform Installer 3.0

但是下面出錯的問題還不知道要怎樣解決？
