Kernel debugger?

[a81]

Hi I just downloaded Dtools and Ive got a noob question for ya
When I open the installer it says that I shouldnt run it if i got a Kernel debugger on my computer.. Ive no idea what that is but I searched my comp for "kernel" and got a few matches.. one program named Ikernel, one .rgs file with the same name, and a few .dll files named Ikernel and kernel32.. does this mean I shouldnt run the installer?
again, sry for the n00bish question hehe

If you don't know what a kernel debugger is, you probably don't have any installed, so press ok to that message and continue installation.
