Can't Initialize Daemon Tools

[holtvg]

I installed daemon tools 4.0.3, rebooted my computer and clicked on the shortcut and it couldn't initialize it. It gives me the following error message:
Initialization error.
This program requires at least windows 2000 with sptd 1.24 or higher. Kernel debugger must be deactivated.

It can't be that my operating system is too old, because I have windows xp professional sp2, tried redownloading it and reinstalling it but it does the same thing, and my computer meets the requirements. What's the problem?

Kernel Debugger is an extra Program that you must install, i think you didn´t have installed it on your maschine.

Its another problem that i dont know. Work DT 4.00 HE for you ?
