Steps 1 - 9 install the driver supplied with the keyboard, the only odd thing is to continue the installation if you are presented with a message about digital signature. Win 98 is finished at step 9.

Below are the next steps required for Win 2000 and XP. I followed these, step by step, with no installation problems on Win XP. Good luck.

These steps are for Win 2000 and XP only

10. Press the Start button, open the Control Panel and open Sound and Audio devices.
* When 'Sounds and Audio Device' does not appear, select 'Sounds, Speach, and Audio Devices' and then open 'Sounds and Audio Device'.

11. Select the hardware tab.

12. If 'Panasonic USB MIDI' does not appear in the device box, perform the following procedure. (If 'Panasonic USB MIDI' appears, the installation is finished, so the following procedure does not need to be performed.)
