How to activate advertisements

I want to activate the standard advertisment “build your PC”. Is there a add-on to click before showing. It is no not showing

I just tried in the sub-menu advertisment etc.

  1. Which version of CS-Cart?

    -----a. If 1.3.5 SP2, then use Manage Ads.

    -----b. If 1.3.5 SP3, then use Listmania.
