Telerik Reporting REST WebAPI service has dependency on System.Web.Http.dll 22.214.171.124
, which is why the later is loaded. If the assembly is already referenced in the project and has different version, you will need to add proper binding redirects per How To: Add Telerik Reporting REST Web API to Web Application.
The problem is not reproducible in our tests. Thus please check if deploying the current test project runs as expected in test environment without installed Telerik Reporting and Telerik Data Access on the machine.
If the problem still occurs with the suggested deployment test, please open a support ticket and send us the tested project to check its settings.
