Configuration Button Disabled on new IIS site

I created a new web site in IIS and then installed a web site and went to the properties page. I needed to edit the config so I went to the ASP.Net tab and found that the Edit Configuration button was disabled. I searched the web using: “new IIS” web.config “button is disabled” “Edit configuration” and found nothing. It is a simple issue: The Asp.Net version must be set to 2.x not 1.x in the properties page. There now the issue is searchable, and I will know what to do next time!
