Errors while using Daemon tools

In a short story, I need to fix the windows installer but suddenly an error shown underneath appears in my personal computer.

Initialization error.
This program requires at least Windows 2000 with SPTD 1.21 or higher.
Kernel debugger must be deactivated.
While employing the DAEMON Tool and initialization error materializes. The program needs Windows 2000 with version SPTD 1.21 or above. Is there a need to deactivate the Kernel debugger? Guys please provide solution to repair this problem especially those who are experts.
