The page you are requesting cannot be served because of the extension configuration. If the page is a script, add a handler. If the file should be downloaded, add a MIME map.

1. On the server with IIS installed start a command window as an Administrator. 


2. Go to the 'C:\Windows\Microsoft.Net\Framework\v3.0\Windows Communication Foundation\' directory, or 'C:\Windows\Microsoft.Net\Framework64\v3.0\Windows Communication Foundation\' if using a 64bit operating system. 


3. Run this command 'ServiceModelReg -i'
