NET 3.5 Framework installation failed. MSI returned error code 1603

装NET 3.5 Framework 失败看日志如下

"The following component failed to install: Microsoft .NET Framework 3.5"

When i checked the error log this appears:

"04/03/10,12:30:11] Microsoft .NET Framework 3.5: [2] Error code 1603 for this component means "Error grave durante la instalación. " [04/03/10,12:30:12] Microsoft .NET Framework 3.5: [2] Setup Failed on component Microsoft .NET Framework 3.5 [04/03/10,12:30:13] VS70pgui: [2] DepCheck indicates Microsoft .NET Framework 3.5 is not installed.

上网搜了一下，原来要先装frameworks 2.0 SP1 and framework 3.0 SP1.

1.清理：In order to perform a clean uninstall of the framework 2.0 I used this application : http://astebner.sts.winisp.net/Tools/dotnetfx_cleanup_tool.zip.
2.下在Framework 2.0 SP1：http://download.microsoft.com/download/0/8/c/08c19fa4-4c4f-4ffb-9d6c-150906578c9e/NetFx20SP1_x86.exe
3.下载Framework 3.0 SP1：http://download.microsoft.com/download/4/9/0/49001df1-af88-4a4d-b10f-2d5e3a8ea5f3/dotnetfx30SP1setup.exe

然后就可以装3.5了
