Introduction:

Here I will explain how to solve iis 8.5 detailed error “HTTP error 404.3 – Not Found (the feature you are trying to use may not installed or the appropriate MIME map is not enabled for the website or application)”. Actually this problem occurred when .NET framework 3.5, 4.5 not installed but using those frameworks in applications. To fix this problem we need to enable asp.net 3.5 or 4.5 version frameworks using Turn windows features on or off in control panel.
