If you have Windows 7 Ultimate, you should have access to XP mode, which should allow you to run the program without issue. If you don't, you've got three choices:
  1. Install a virtual machine package such as VMWare, and then install a copy of Windows XP into the virtual hard drive.
  2. Dual boot Windows XP and Windows 7.
  3. Find a used netbook or laptop with Windows XP preinstalled and use it with the software.
