Backing up installed software to a portable HD

I am preparing to format my HD in order to "clean" install  Windows 2000 Pro instead of Win ME.  I have a credit card processing program that I lost the original install disc for.  I have a portable HD that I am backing up to, How can I back up this software and be able to reinstall it on my new OS

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

In short,
you can't

there are driver files that are rquired to be installed with the software as well as information files that make the software work and communicate with your OS. and to make it morse it was installed on WindowsME and even if you knew exactly what files to copy they would be for the wrong Operating System. there are different drivers for diffenent Systems and these Operating systems process information in totally diffenent ways.

This is Probably not the information you wanted to hear right now but as you now there are absolutely  no upgrades for WindowsME...

I'm sorry to hear that your using that OS....

I would scrap the system anyway and install windows 2000. I'm sure you will find another copy of the program somewhere else somehow!

good luck!
