Greetings --
WinXP, like WinNT and Win2K before it, will not allow software
applications to directly address hardware devices. This is one of the
reasons the WinNT family of operating systems is so much more stable
than Win9x. You'll need to acquire a version of your application that
is designed specifically for WinXP. Contact the manufacturer of the
application to see if any updates, patches, or upgrades are available.
