Trouble running old DOS program

I have an old DOS program (EED3) that uses expanded memory page frames. I tried unsuccessfully to make it run on Dell machines and then found out while searching MS’s KB that a Dell machine can’t run EMM386 because of EMS page frames. I then tried loading my program on an HP Pavilion a couple of years old that I have at home. It worked well so I bought a HP Vectra420 at work and now it installs but I get an “emm386 has detected error #1 in an application at memory address C000:1208” when I try to start the program. I’ve adjusted my config.sys file many diferent ways but have had no luck in getting the program to run. Any ideas anyone?
