Problem while running a page from Development Environment

Hi everyone,

I have a problem while trying to run a page from the Nav 2013 Development Environment.
Configuration: Nav 2013, SQL Server 2008 R2.
The RTC client works just fine, the problem occurs when I try to run a page from the Development Environment, I get the following error:

The client could not establish a connection to the Nav service.

FaultCode = 'InternalServiceFault'

Reason = 'The server was unable to process the request due to an internal error. For more information about the error, either turn on IncludeExceptionDetailInFaults (either from ServiceBehaviorAttribute or from the <serviceDebug> configuration behavior) on the server in order to send the exception information back to the client, or turn on tracing as per the Microsoft .NET Framework 3.0 SDK documentation and inspect the server trace logs.'

I have Nav 2009 R2 installed on the same machine,I think may be the problem is coming from that…but I am not sure…
PS: I installed Nav 2013 first, then Nav 2009 R2…

So what shall I do???

Please install NAV2009R2 first and then NAV2013 later…

As you have installed NAV2009R2 latest, the registries must have NAV2009R2 path so thy will try to run the page in NAV2009R2…

Thank you for your reply…

but if I do that, would I be able to run pages correctly from NAV 2009 R2???

and what are the registries you mentionned???

Yes but you can run them from RTC directly not from Classic Client…

Ok…What about the registries you mentionned???
