how can i active slider revolution? and where is parallax option ?

Hello,

WPBakery Page Builder and Revolution slider come bundled with our theme but they can’t be activated with our purchase code. Actually, you don’t need to do this. Only in case you want to get free premium support from its author, you can purchase it from Codecanyon. But it is not necessary since we will always provide you with the latest updates.

In order to configure parallax effect in Slider Revolution please refer the instructions provided in the documentation:https://www.themepunch.com/slider-revolution/on-scroll/#parallax

Best Regards
