When you go to the Windows/Start/Programs/Genealogy menu and select "browser setup", it detects if you have Netscape Navigator or Internet Explorer (or both) installed on your computer. The Browser will scan your hard drive to find the files needed.You can choose which of these you want to connect to in the UFTree web site. Once you have opened the Browser Setup, follow the directions given. When it is nearly done, it will show you the default location on your hard drive and then click FINISH. That should do it for you.
