I got this working when i change the app pool's .Net framework version to my application's .net framework version.My application's framework version was 4.0 but app pool's setting was defaulted to 2.0. I had to change it to 4.0, then it worked fine.
+1 with @Dablue, IIS 8.5 does not support the aspnet_regiis command anymore. For me, the issue is resolved by installing the "Asp.Net 3.5" or "Asp.Net 4.5" underWeb Server > Application Development.
