Download file link on page node

I want to have on a page node a link to a file. It is a download page for my software. I also want to track file download count so I use download_count module. This module need to have download method to private.
The problem is that unauthenticated users cannot download the file. They got access denied error.

Does anybody know how I can solve this issue? Or if possible to give me a better solution. Also how can I set a relative link to a file from a file system so that I can use the same file in two download pages.

Thanks a lot,
Radu
