      I am getting error Asp.net 4.5 has not been registered on Web Server . You need to manually configure your web server for Asp.Net 4.5 in order

    for your site to run correctly. I have run aspnet_regiis -i but still not working

    Hi JagjitSingh,

    According to your description, I suggest you could firstly make sure you have installed the asp.net 4.5.

    Besides, as far as I know,  on Windows 8.1 and Windows 10 which wouldn't support the aspnet_regiis -i approach.

    So we should install it from Control Panel.

    I suggest you could follow below steps to install it.

    Go to Control Panel, Click On Programs locate the "Turn Windows features on or off" option Under Programs and Features and drill down as follows:

    Internet Information Services -> World Wide Web Services -> Application Development Features and check the "ASP.NET 4.5" option. In checking this box, other options such as ".NET Extensibility 4.5" and the ISAPI options will be checked automatically.

    At last, restart the computer.

    Best Regards,
