What is the program called? There may be a way to get it working by using virtual PC software.
The only way to go from 64bit to 32bit is by doing a clean installation of Windows with a 32bit install disc. Since you bought the laptop with Windows pre-loaded, chances are you don't have any install media, so you'll then have to buy another copy of Windows.
You can try running it under DOSBox. 64 Bit OS's can run 32 bit programs. I have a feeling that DOS program you have is 16 bit.
