解決asp.net 3.5sp1錯誤

       因為asp.net mvc 1.0正式版要求在vs 2008 sp1 運行，必須安裝.net 3.5 sp1,安裝過程中出現錯誤如下：

       [04/03/09,13:13:58] Microsoft .NET Framework 2.0SP1 (CBS): [2] Error: Installation failed for component Microsoft .NET Framework 2.0SP1 (CBS). MSI returned error code 1058
[04/03/09,13:46:05] Microsoft .NET Framework 2.0SP1 (CBS): [2] Error: Installation failed for component Microsoft .NET Framework 2.0SP1 (CBS). MSI returned error code 1058
[04/03/09,13:46:27] WapUI: [2] DepCheck indicates Microsoft .NET Framework 2.0SP1 (CBS) is not installed.
[04/07/09,11:01:12] Microsoft .NET Framework 2.0SP1 (CBS): [2] Error: Installation failed for component Microsoft .NET Framework 2.0SP1 (CBS). MSI returned error code 1058
[04/07/09,11:01:32] WapUI: [2] DepCheck indicates Microsoft .NET Framework 2.0SP1 (CBS) is not installed.

       最後在看安裝說明時，發現要把系統的更新開啟，開啟系統更新後，Microsoft .NET Framework 3.5 SP1更新成功。 我習慣關掉系統更新，因為以防哪天微軟把我這個盜版使用者揪出來了。
