I am not sure on this, but if it were me, I would go to Control Panel and Programs - Uninstall prgrams, look for ION EZ converter and either UNinstall it, or click that and then click Repair in window that comes up. then REINSTALL with your disk or dowload. reinstall the drivers and converter On the disk you get with the product there are 2 installations the first is the drivers the next which you have to do separately is the software program
hope this helps
