I hope you are well today and thank you for your question.
If you have not purchased slider revolution plugin and using the plugin bundled with the theme then you are not direct customer of that plugin so can not activate that plugin.
Please see more information about this on the following pages.
To use the plugin you don’t need purchase code, you can just install and activate the plugin from Appearance -> Install Plugins

We would be more than happy to help you with your new thread.
Sorry but in the path you mentioned I can’t find a builder plugin, (attached the screenshot) do I need to delete mine before? I’m sure that I’ve installed the current WpBakery plugin with the theme..
Let me know
thanks a lot
