如何解决IE9卸载后出错无法打开

IE9是微软最新的网页浏览器，目前处于BETA1，它提供了丰富的HTML5体验，快速的性能，以及华丽的外观，但是在很多用户卸载IE9后却无法回滚到IE8.0甚至C:\Program Files\Internet Explorer里无任何可执行文件了，如果重新安装IE9则出现下图中错误Internet Explorer did not finish installing

我们看到重新安装IE9需要确保几个事项

Setp1、控制面板添加删除程序中确实移除了IE9的更新包

手动移除方法参考命令：

FORFILES /P %WINDIR%\servicing\Packages /M Microsoft-Windows-InternetExplorer-*9.*.mum /c “cmd /c echo Uninstalling package @fname && start /w pkgmgr /up:@fname /norestart”

Setp2、使用Windows7原版DLL复制替换

C:\Windows\SYSTEM32\ieframe.dll复制到Windows7的C:\Windows\SYSTEM32

C:\Windows\SYSTEM32\mshtml.dll复制到Windows7的C:\Windows\SYSTEM32

Setp3、重新安装IE9.0
