I am afraid this is not possible. I will explain why.
As authors who wish to offer Visual Composer plugin included in our theme, we purchased an extended license from Visual Composer. This is a single license code that can be used only to offer the plugin Visual Composer in our theme as included.
The extended license cannot be activated on multiple domains (it is a restriction of license regulations from theme forest).
This is the same for every wordpress theme that offers visual composer included in a theme purchase.
For the Custom Templates Visual Composer offer, they demand you add a license key before you get access to the templates. Since the license we have cannot be used on multiple domains, you would have to buy a separate license to use this feature.
What we can offer for clients who wish to use Visual Composer included in the theme is:
– free updates (through theme updates)
– the option to use the visual composer plugin for free with Wp Residence without having to buy a separate license.
