        private static string _iisRegKey = @"Software\Microsoft\InetStp";

        public static bool IISInstalled()

        {

            try

            {

                using (RegistryKey iisKey = Registry.LocalMachine.OpenSubKey(_iisRegKey))

                {

                    return (int)iisKey.GetValue("MajorVersion") >= 6;

                }

            }

            catch

            {

                return false;

            }

Run web application as administrator writes in IIS.

Some time we need to run our web application as administrator mode. One of my application run time I want to create some file in my web application. While creating the txt file in my root folder in c drive C:\inetpub\wwwroot I got security exception error. The reason is I don’t have administrator permission to write text file in my application. For that I have added the Identity impersonate is TRUE in the web config file.

<system.web>

    <identity impersonate="true" userName="sa" password="pwd"/>
