WorkFlow Manager 1.0 Configuration Exception

I have been working on SharePoint 2013 project, and one of the requirements is installing and configuring workflow manager, according to our topology design, there is a separate server for workflow manager. The installing started smoothly by running Microsoft Web Platform Installer, workflow manager 1.0 component has been installed successfully, and then I tried to install Cumulative Update for Service Bus 1.0 by using Microsoft Web Platform Installer (to install Cumulative Update 2 for Workflow Manager 1.0 we must install Cumulative Update for Service Bus 1.0), when I started to search about the component using Microsoft Web Platform Installer, it appears Cumulative Update for Service Bus 1.0 already installed ! any way , Cumulative Update 2 for Workflow Manager 1.0 has installed successfully by using Microsoft Web Platform Installer Also . Finally, I started to configure workflow manager farm, create workflow instance databases and configure service bus using workflow manager configuration manager wizard , at first steps everything is fine until “Get Service Bus Client Configuration ” step of the configuration , it thrown  the following exception

The remote server returned an error: (400) Bad Request. The api-version in the query string is not supported. Either remove it from the Uri or use one of ‘2012-03’

 

That issue Looks like a service bus version issue. So you have to ensure that Cumulative Update for Service Bus 1.0 is already installed on this server, try using Microsoft Web Platform Installer or you can download that component directly from Microsoft website http://support.microsoft.com/kb/2799752 then install it . i solved my issue by this way
