Hi @Sharad,
We understand that it is asking for a registration key, and we are here to assist you.
Please read detailed information about bundled plugins here https://help.market.envato.com/hc/en-us/articles/213762463-Bundled-Plugins
Free versions of the WPBakery or Revolution slider or any other premium plugin just do not exist!
We would like to inform you that all premium plugins included with our theme are external products for which we have secured the Extended License, allowing us to incorporate them into our theme. Please note that registration of these plugins is not mandatory, as they are fully operational without activation.
The activation feature within these plugins is designed for customers who wish to receive automatic updates and direct support from the plugin developers. Additionally, plugin authors may introduce exclusive or just additional features to encourage customers to purchase the plugins directly from them. Unfortunately, this is a situation that affects not only us but all theme authors on the ThemeForest platform.
Unfortunately, if you want to import templates from the Revolution slider or WPBakery template library you need to buy the personal license of plugins. Extra features do not come with the extended license, this is Revolution slider authors rules. We and all theme authors on the ThemeForest platform can do nothing about this.
Best Regards,
8Theme’s Team
