network request error when running feedreader from a network drive


I try to install feedreader on a network drive.
Problem with the installation is you can only choose between creating a data folder in the application dir or in the local users dir ('application data'). When I choose to create the data folder in the appl dir and then copy the whole thing to a network drive, I get this message when running the exe: [Unable to complete network request to host "xxxxx". Failed to establish connection. The system cannot find the file specified.]
When I try this with USB flash memory: no problem. Why is this not working with a network drive?
