We're supposed to carryout Performance Testing on a 64 bit standalone desktop application on 64 bit OS built around .Net 4.0 and HTML5 with WPF & WCF(it's a ClickOnce Application)..

While using LoadRunner 11.5 for recording, application is NOT launching in the foreground but in the background, the respective process is running in Task Manager.

We've Googled and found out that a ClickOnce Application cannot be recorded using the general installation path(E:\xxx\xxxx\xxxx.exe)

Possible workaround might be going forward with the .exe file in the Deployment Folder. But we're unable to launch the application even after using the .exe from DeploymentFolder path: "C:\Users\username\AppData\Local\Apps\2.0\obscure_dir_name1\obscure_dir_name1\ "

We also tried WebServices Protocol where in we're getting an error "The HTTP request is unauthorized with client authentication scheme 'Anonymous'. The authentication header received from the server was 'Negotiate,NTLM'"

We've also tried some permutations and combinations with ManageServices>Protocl & Security>Scenario>CustomBinding...etc but of little/no use

The following info is regarding the Binding Mechanism used in the Development of the Application

<wsHttpBinding> <binding name="proposal"maxReceivedMessageSize="2147483647"> <readerQuotas maxArrayLength="2147483647" /> <security mode="Transport"> <transport clientCredentialType="Windows" /> </security> </binding> </wsHttpBinding>

Any help in solving these issues is deeply appreciated.

Thanks in advance.
