How can I stop a process from loading twice?

[Twiller]

Hi,

For some reason INCD.EXE, a packet-writing piece of software for Nero 6, insists on loading into memory twice at startup, putting 2 icons in the taskbar (Windows XP Home). I can open the task manager, go to the Process tab, and shut one of the instances down, and InCD works just fine, so it's not necessary to load twice in order to work properly. What's causing this and how can I stop it?

Thanks.

Is it in the registry and the startup folder?

Not the startup folder, so I guess it starts from the registry. The program Nero itself doesn't load, just this one process (it allows treating a CD-RW disc like a drive for file management).
