    Umbraco Manual Install

    I have a fresh Windows Server 2012R2 web server, with IIS working. I have followed these instructions 2 different times with the same result, "500 - Internal server error".

    I have placed the Umbraco root files in the wwwroot and given the IIS_USRS modify permissions to that folder.

    Update, I tried to move the Umbraco extraceted directory and mapped a new site in IIS with these results:

    HTTP Error 500.19 - Internal Server Error

    The requested page cannot be accessed because the related configuration data for the page is invalid.

    Detailed Error Information:

    Module IIS Web Core

    Notification BeginRequest

    Config Error This configuration section cannot be used at this path. This happens when the section is locked at a parent level. Locking is either by default (overrideModeDefault="Deny"), or set explicitly by a location tag with overrideMode="Deny" or the legacy allowOverride="false".

    I think your IIS install may not be correct. I googled your error and it seems to be related to a bad configuration of IIS.

    Also check that your app pool is setup correctly.

    So, I enabled all of the ASP.NET 4.5 Features and it worked...

    Just to clarify - how to enable all of the ASP.NET 4.5 Features :

    I found this at

    In PowerShell, as administrator, run dism /online /enable-feature /all /featurename:IIS-ASPNET45

    This did the trick for me.
