Unable to set Safe Path for "Shipment for Virtual Products"

[sgower]

When I try to set my Safe Path I keep getting the following error:

Warning, the Safe Path is not accessible (does not exist or no permission), for safety reasons it is very important to create a folder in a path not accessible by an URL, create also a folder invoices in it to store your sensitive data secure.

What do I need to do to be able to set my safe path?
