Issue with Crystal Report compatibility (version 13.0.20.0) to new WPF Application

In existing web project, Crystal Reports(CR) are generated using version 13.0.2000.0 and it needs CR Runtime Engine 32 bit installed on the machine. The (CrystalDecisions) dlls are referenced from a folder 'dependancy' in the project. The project is hosted locally and Web Service is exposed for others to get reports.

Now, I have created WPF project and have consumed the web service. My plan is to get the Crystal Report and show it in my WPF App.

I am facing following issue: 1. To add Crystal Report Viewer control (in toolbox) in WPF project, I need software CRForVS. I am not getting its older version that will support CR 13.0.20.0. If I install relevant version of CRForVS i.e v20, it seems to be referring Crystal Decisions 13.0.35.0. Which is not compatible with 13.0.20.0. And I get exceptions like 'Could not load file or assembly 'CrystalDecisions.CrystalReports.Engine, Version=13.0.2000.0, Culture=neutral, PublicKeyToken=692fbea5521e1304' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)'

I am reluctant to upgrade existing version 13.0.20.0 in Web app because it is a legacy app. Is there any other way? Or am I missing something?
