Hi I have just attempted to install DNN 5.2 on Windows 7 Pro. I followed you video tutorial but I now get a nasty error when trying to run localhost for the first time. Any idea what could have gone wrong? Error Summary 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 Handler Not yet determined Error Code 0x80070021 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". Config File \\?\C:\DNNSites\GNR5\web.config Requested URL http://localhost:80/gnr5 Physical Path C:\DNNSites\GNR5 Logon Method Not yet determined Logon User Not yet determined Config Source 90: 91: 92: Links and More InformationThis error occurs when there is a problem reading the configuration file for the Web server or Web application.

Double check the correct permissions are set on the folders and files in the install.

Try installing using the method in the final video where we manually create the database and setup the user account for the database.
