I'm using Windows 98 first edition, and after having multiple issues with tying to install and uninstall NAV Professional 2004, Systemworks 2004, and Nortons Personal Firewall 2004, I am being told that the virtual driver; SymTDI is missing. How do I get this driver, where does it go, and what keys have to be added to the system registry to get it work? I've visited the Symantec site and their supposed work-arounds leave me in dead end loops with much frustrations and more installs and uninstalls!
