新机子 成功装了vs2010，然后装sql2012提示让装vs2012sp1，下载了sp1,装的时候，装到最后一个包NDP40-KB2468871的时候报错了 KB2468871安装失败
错误：
Exe (F:迅雷下载VS2010SP1dvd1NDP40-KB2468871.exe) failed with 0x8007066a - Windows Installer 服务无法安装升级更新程序，因为被升级的程序可能会丢失或是升级更新程序可能更新此程序的一个不同版本。请确认要被升级的程序在您的计算机上且您的升级更新程序是正确的。 . Final Result: Installation failed with error code: (0x8007066A), "Windows Installer 服务无法安装升级更新程序，因为被升级的程序可能会丢失或是升级更新程序可能更新此程序的一个不同版本。请确认要被升级的程序在您的计算机上且您的升级更新程序是正确的。 " (Elapsed time: 0 00:42:09).
解决办法：
下载.NET Framework 4 即这个包dotNetFx40_Client_x86_x64.exe 进行修复，修复完成，使用windows update更新net的补丁（重要的就是framework4.0相关的补丁），补丁安装完成然后打开iso中的 NDP40-KB2468871.exe 点击单独安装 ok 然后就可以安稳的安装sql2012了。。。。。。
