问题：framework_3.5_sp1安装失败怎么办？我以前安装过f 
我以前安装过work可能是没更新的缘故，现在好多程序不能用了。所以下载了framework_3.5_sp1线重新安装，可是安装一半就出错了。卸载了原来安装过的framework，可还是安装不上framework_3.5_sp1。我现在该怎么办？请高手帮忙解决。谢谢啦以下是安装失败的错误报告：[09/05/09,21:03:10] Microsoft .NET Framework 3.0a: [2] Error: Installation failed for component Microsoft .NET Framework 3.0a.我以前安装过work可能是没更新的缘故，现在好多程序不能用了。所以下载了framework_3.5_sp1线重新安装，可是安装一半就出错了。卸载了原来安装过的framework，可还是安装不上framework_3.5_sp1。我现在该怎么办？请高手帮忙解决。谢谢啦以下是安装失败的错误报告：[09/05/09,21:03:10] Microsoft .NET Framework 3.0a: [2] Error: Installation failed for component Microsoft .NET Framework 3.0a.

回答：你试试用2.0版本
一般安装不上都是系统有问题
