Make sure that you have the latest version of the Easy CD Creator 5 software installed. You should not need any patches to run it in WinXP Pro.
If you have an earlier version install disc, after the initial install and before rebooting, install the latest v5.3.4 Update
and then reboot. Everthing should then be recognized and work properly.
Easy CD Creator 5 works fine with WinXP Pro.
