[Computer] Unsuccessful Attempt to Install DocuPen's PaperPort Software

I have repeatedly and unsuccessfully failed to install the driver and
application software for my DocuPen portable scanner. The installer
software is pretty brain dead ? it does not give me any indication of
process or progress. Finally, Windows XP raises a dialog box telling me
that the DLL the installer is attempting to install is not a valid Windows
application. Time to contact the DocuPen support staff or return the
uninstallable product (I fear the CD may be bad). :-(
