If you  see this error you havent installed the prerequistes for ASP.NET 4.Try this
  1. Open Visual Studio Command Prompt
  1. Type the following: 
  1. aspnet_regiis.exe -i
  1. Run the command
  1. Try your service again... 
  1. Happy Face - it should be working :-)
 This basically installs the necessary ASP pieces to get your service up and working!
