Bonjour de Montréal, 'colorgreen'
... notice that this is your first post so welcome to the board
As for your question, go to Roland's site, download and install the GX-24 driver for WinXP and away you go. I see you have Corel so you can cut directly from there; I'm not familiar with the others but I would expect them to work as well.
