我在安装.net 3.0 框架时报上面错误，请问是什么原因呢？我该怎么解决呢？郁闷啊。。。。。。
多谢大家，给帮帮忙吧
------解决方案--------------------
用.NET清理工具(http://files.cnblogs.com/CuteNet/dotnetfx_cleanup_tool.zip)把之前安装的清理后再安装试试
------解决方案--------------------
系统重装了
------解决方案--------------------
不知道什么原因,建议重做系统重装VS
------解决方案--------------------
安装包没问题吧，有没有试过在别的电脑上安装成功
------解决方案--------------------
其它电脑可以安装，就那台电脑不能安装的话，估计是系统问题了，至于具体问题，只能你自己分析排除了
------解决方案--------------------
不知道楼主是什么系统，好像vista是无法安装3.0的
检查一下3.0的版本，是64位的系统安装的还是32位系统安装，选择正确的安装
尝试安装windows install 3.0，再安装3.0试试
还有一种可能，系统里装了 SQL 2005 SP2,导致 .Net 2.0 SP1 无法安装造成失败
好像以前还看过一个博客，说是因为权限问题，无法安装，具体的忘记了
最好检查一下错误日志，看是否有详细的错误
