Usually Pro is regarded as being an upgrade from Home. You're getting the error message because you're trying to downgrade Pro to Home.
I'm assuming you would prefer to have the Pro key instead of installing Home. Did you buy the computer new or used? If new, you should be able to contact the company you bought it from to get a key. If used, you may have problems. It's possible you have an illegal version of Pro. As a quick check, go to Microsoft's web site and run the validation tool. If it says your system is valid, contact MS and ask them for help with the key. If your system isn't valid, you're probably stuck with Sue's suggestion of installing an older version of Windows and then upgrading it to Home.

Just run belarc and make a report. You will find the XP keycode in there.
