Windows 2000me and incorrect dos version

I'm seeking some help on a problem with our office network system. We are still using a dos based estimating program which uses the old backup and restore commands. Our present network is a peer to peer windows 95 system. we are adding 2 new computers with windows 2000me OS. I have copied the backup and restore files to the command directory as we did when we went to the windows 95 system. I also ran setver to establish those files as dos version 6.22 as before. however I can only get the message "incorrect dos version" when attempting to execute those files. when I checked the setver, the files have been set to 6.22 but i get a message that says that setver is not loaded and that I need to load setver in the config.sys file. I have tried device= and load both with and without paths but still get the same error message. Since the setver file is still a part of Windows 2000me I would think that it should be available to be loaded. how do i get the file to load? Thanks for the help.
