需要帮助设置ASP.net 3.5(截图)

我正试图在一台计算机上开发一个网站,在我的家用电脑上工作.旧电脑运行的是ASP.net 3.5.

在我的新计算机上,安装IIS和ASP.net 3.5之后：

我收到以下错误：

检查应用程序池后,它说它正在运行ASP.net 2.0：

而且没有选择将其更改为3.5：

我已经检查了已安装的.net版本的regedit,并在那里列出了已安装的3.5.我似乎无法使我的网站运行3.5,或运行没有任何奇怪的IIS错误消息.

这个帖子：http://forums.asp.net/p/1184937/2018939.aspx表明2.0显示是正确的,我的问题是为什么网站没有运行？

这是我的web.config文件：
