大家好,乐天来为大家解答以下的问题，关于netframework4 5，netframework4安装失败这个很多人还不知道,现在让我们一起来看看吧！
1、前装viusal stuido 2010 ultim一直失败，而且等的时间特别长，在安装.net framework 4.0时就失败……后来就单独安装.net framework 4.0。
2、结果还是失败，出现hresult 0xc8000222错误代码，去官网上查找。
3、发现作如下操作步骤即可this behavior may occur if the temporary folder of windows update has been corrupted. we can refer to the following steps to rename this folder. please be assured the folder will be created again when we visit the windows update site again.1. click start, run, type: cmd and press enter. please run the following command in the opened window.net stop wuauserv2. click start, run, type: %windir% and press enter.3. in the opened folder, rename the folder softwaredistribution to sdold.4. click start, run, type: cmd and press enter.please run the following command in the opened window.net start wuauserv开始->运行->net stop WuAuServ2、开始->运行->%windir%3、将文件夹SoftwareDistribution重命名为SDold4、开始->运行->net start WuAuServ然后再安装就可以成功了，亲测，我今晚刚装上。
