Filename List function in Kutools for Excel

Hi, I downloaded Kutools for Excel for a specific requirement i.e to list all files in folder and subfolders.
I did a test run on my home computer (60 day free trial), worked perfectly well.

Downloaded it on my office PC. Here I wanted to get list of all files in folders/subfolders that are located in a shared network drive. When I try to look for the shared network folder from Excel, I cannot see the shared network folder.
How can I make this work?

Please advice. Thanks.
