　　.NET Framework是Windows的托管执行环境，可为其运行的应用提供各种服务，因此不少软件安装的前提是需要系统先配置.NET framework，但是近期有用户遇到了Win7旗舰版无法安装net4.0的情况，那么应该如何解决呢？我们来看看吧。

　　方法一：

　　1、我们先在键盘上按windows键+R键。

　　2、在运行框中输入cmd后，点击【确定】。

　　3、在弹出的以下窗口中，输入net stop WuAuServ后按回车键。

　　4、然后我们返回到运行窗口，输入%windir%后点击【确定】。

　　5、进入到windows系统目录页面，我们找到SoftwareDistribution文件夹，将文件夹名修改成SDold。

　　6、接下来，我们在运行窗口中输入cmd后，点击【确定】。

　　在以下窗口输入net start WuAuServ后按回车键，这下我们再次安装net4.0就可以正常安装啦！

　　方法二：

　　1、按Windows+R 输入services.msc，点击打开。

　　2、打开服务，点击服务（本地）。

　　3、在右侧找到Windows Update，点击选中。

　　4、点击左上角，点击停止此服务。

　　5、在资源管理器中，打开电脑C盘。

　　6、打开Windows文件夹。

　　7、找到SoftwareDistribution打开。

　　8、将SoftwareDistribution当中Download和DataStore进行删除。

　　9、按照如上步骤重新启动Windows Update。
