成功解决win7不能重装ie9的问题
win7，64位旗舰版，安装sp1前，因为怀疑ie9不是64位的，果断删除（在升级补丁里可以看到）。之后后悔莫及。重新下载安装，失败，提示未知错误，重启不重启的，折腾很久，无果。

sp1安装成功后，仍然不能。遍寻网络资料，发现可以检查“c:\windows\ie9_main.log”，里面有每次安装失败原因的记录。如下：
过长，有删减。

能看懂的一目了然了，在网上看到一个办法，就是在安装ie9期间，手动找到ie的临时安装解压路径（名字可能不太一样），我的是“C:\Windows\TEMP\IE9C581.tmp\”，找到IE9-neutral.Downloaded.msu，手动安装，结果显示不能成功安装。重新看ie9 log中以前的记录，有“INFO: Process exit code 0x00003715 (14101) “，结合：

两篇文章。考虑可能是语言包的问题，我的系统盘没有备份，但是是旗舰版，直接改为英文系统（change the language user……），下载文件
Windows6.1-KB982861-x86.msu http://go.microsoft.com/fwlink/?LinkId=210143。手动安装运行，中间重启，之后安装ie9，提示语言不对（我安装包选的中文），忽略直接安装。安装成功。安装不成功的时候，安装滚动条在30%提示安装语言包，会直接跳到90%，然后提示失败。安装正确的时候，滚动条在30%~70%都会平滑增长。另外很多帖子说，需要什么四个补丁，我没有用，直接是sp1，都是系统自己下的补丁，只安装重要更新。在中文下，直接安装Windows6.1-KB982861-x86.msu是不成功的。怀疑确实是因为一些原因导致系统语言文件损坏，或者是微软的bug。对了，平台是thiknkpadT410，直接是出厂镜像的专业版，升级到旗舰。
