>After compiling my application into an exe., I ran the setup Wizard and made disk images(4) which I copied to four 1.4 Meg floppies. When I ran the setup program on another computer, I got an error message during setup (disk one) saying: "Bad tag filename in a line of the [source media desciption] section". What's going on here, any clues?

Bill, are any of your file names longer than the standard DOS 8.3 structure? Do any of the directories in your installation files have spaces? Either of these have been known to cause problems.
