error: server side activities have been updated you need to restart sharepoint designer

I have installed VS 2017 with SharePoint Designer 2013 32 bit and when i configure workflow manager, i get this error: server side activities have been updated you need to restart sharepoint designer.

Most of the blogs suggested to uninstall Workflow manager client from Control panel – Programs , but i didnt see it listed there but when i open Web platform installer, i see it installed on my machine.
