解决asp.net 3.5sp1错误

       因为asp.net mvc 1.0正式版要求在vs 2008 sp1 运行，必须安装.net 3.5 sp1,安装过程中出现错误如下：

       [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.

       最后在看安装说明时，发现要把系统的更新打开，打开系统更新后，Microsoft .NET Framework 3.5 SP1更新成功。 我习惯关掉系统更新，因为以防哪天微软把我这个盗版用户揪出来了。
