download product vm2

[peter78]

Hello everyone, I apologize for my English, I'm Italian
My question is:
in previous versions it was possible to do so by checking configurations, and then download
My question was:
1 I would like to add documents to download, what option do I enable to do?
2 I would like only one person of those registered to see the product and buy it consegueza (whether it is always possible to do so)
For example, when I add the file to choose the products that you can see and buy the product, thanks happy holidays
