How to add custom widget zone.

I had issues logging into this forum , seems now cleard.
I bought this plugin , so i can add content to the product detail page. but location that i need to add info , is not available within this plugin.
found an article describing how to add custom zone to the plugin. but I have no clue how to add custom zone into the product detail page.

any chance some one can baby setup me toward this solution .
Thanks.

You have to edit the Product Page template files for single and grouped products.
For Venture theme the files are here: Themes\Venture\Views\Product\

Just copy the line of code for some existing widget zone to your desired location in the file, and then change its name with the name of your new widget.
