    I am attempting to get the demo installed on Windows 7 Professional, but so far have been unsucessful. The latest error is one that I have been unable to work through. If I can at least get the demo installed and working, we will most likely buy the full product, but my timeline is becoming increasingly short.

    Anyhow, the error being recieved is as follows:

    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.

    I am recieving the error after attempting to browse any newly created project. Any help that anyone can provide would be most apprecietated.

    Hi Wesley,

    Try removing the following line from your web.config

    <add assembly="System.Web.Extensions, Version=, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>

    Clean the solution ( right click on the solution file and choose "Clean Solution"). If you are running the website under .NET 4.0, them you are not using the proper build for .NET 4.0 and your project has been compiled against .NET 3.5. Just to let you know that we have a separate builds for .NET 4.0, 3.5 and 2.0

    Another reason for this error is application inheritance of the web.configs.
