Cannot install Plugin

I added the Plugin to my Presentation\Nop.Web\Plugins folder but when I reload list of plugins, I am not seeing the core or the Sales campaign plugin. Not sure what I am doing wrong. Any help is appreciated.

Hi,

Did you follow the documentation of how to install a plugin - http://www.nop-templates.com/how-to-install-a-nopcommerce-plugin ?

Thank you. I have figured it out.
