IIS 10.0 Detailed Error: mimeMap

Hello so I'm pretty new to using IIS and Visual Studio but I've managed to launch one website on IIS but when I try to launch this one I get this error across the page:

enter image description here

Error message:

Cannot add duplicate collection entry of type 'mimeMap' with unique key attribute 'fileExtension' set to '.mp4'

There's a section that reads Config Error:so here is my web.config file:

Could not load type "PresentationLayer.Global"

Check if you namespace is PresentationLayer or is changed? If changed update it in the markup, by right clicking on Global.asax and select "View Markup"

You could add something like this:

<remove fileExtension=".mp4" />

Or, since the MP4 mime type seems to be already present in the roots configuration file, simply omit the whole line:

<mimeMap fileExtension=".mp4" mimeType="video/mp4"/>

If you really want to be sure that the extensions you seem to require are present, this could be a replacement for the staticContent tag:

<staticContent>
    <remove fileExtension=".mp4" />
    <remove fileExtension=".m4v" />
    <remove fileExtension=".3gp" />

    <mimeMap fileExtension=".mp4" mimeType="video/mp4"/>
    <mimeMap fileExtension=".m4v" mimeType="video/m4v"/>
    <mimeMap fileExtension=".3gp" mimeType="video/3gpp"/>
</staticContent>
