关于NET 3.5的求助、

阿荒

据说很多游戏都要求NET 3.5，但是反复各种方法试装了3天了。依旧是无法安装。装3.5的时候错误日记说是因为没装3.0 sp2
NET 3.O依旧是报错无法安装。
[12/22/11,23:40:31] Windows Presentation Foundation: [2] Error: Installation failed for component Windows Presentation Foundation. MSI returned error code 1603
[12/22/11,23:40:58] WapUI: [2] DepCheck indicates Windows Presentation Foundation is not installed.
上面是报错日记文件
于是试着直接装4.0但是还是不行。。。又报错。。。
