My systems do not have parallel ports. How can I run Service Center?

The DOS portion of Service Center requires a parallel port for the dongle (software key), and cannot be run on a system without a parallel port. An optional USB licensing dongle is available that allows the Windows portion to run on systems without a parallel port. Contact servicecenter.sales@pc-doctor.com for more information.
